As such, it plays an important role in mechanical engineering, computer graphics, and computer vision. In this chapter, we study motion-based segmentation of 3D articulated shapes. We formulate motion-based surface segmentation as a piecewise-smooth regularization problem for the transformations between several poses. Using Lie-group representation for the transformation at each surface point, we obtain a simple regularized fitting problem. An Ambrosio-Tortorelli scheme of a generalized Mumford-Shah model gives us the segmentation functional without assuming prior knowledge on the number of parts or even the articulated nature of the object.

Following the success of this approach in image analysis, there is a growing interest in finding analogous methods in the 3D world. Maximally stable component detection is a low computation cost and high repeatability method for feature detection in images.In this study, a diffusion-geometry based framework for stable component detection is presented, which can be used for geometric feature detection in deformable shapes.The vast majority of studies of deformable 3D shapes models them as the two-dimensional boundary of the volume of the shape. Recent works have shown that a volumetric shape model is advantageous in numerous ways as it better captures the natural behavior of non-rigid deformations. We show that our framework easily adapts to this volumetric approach, and even demonstrates superior performance.A quantitative evaluation of our methods on the SHREC’10 and SHREC’11 feature detection benchmarks as well as qualitative tests on the SCAPE dataset show its potential as a source of high-quality features. Examples demonstrating the drawbacks of surface stable components and the advantage of their volumetric counterparts are also presented.","lang":"eng"}],"language":[{"iso":"eng"}],"date_updated":"2025-01-16T15:50:22Z","article_processing_charge":"No","type":"book_chapter","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","title":"Stable Semi-local Features for Non-rigid Shapes","alternative_title":["Mathematics and Visualization"],"doi":"10.1007/978-3-642-34141-0_8","citation":{"ista":"Litman R, Bronstein AM, Bronstein MM. 2013.Stable Semi-local Features for Non-rigid Shapes.

Then, a parametric family of pursuit processes is derived from the iteration of the proximal descent method for solving this model. We present several experiments showing successful results and the potential of the proposed framework. Incorporating discriminative learning makes the proposed method significantly outperform exact NMF algorithms, with fixed latency and at a fraction of it's computational complexity.","lang":"eng"}],"date_updated":"2024-12-04T13:34:16Z","article_processing_charge":"No","type":"conference","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","date_published":"2013-10-21T00:00:00Z","publication_status":"published","publication_identifier":{"eissn":["2379-190X"],"eisbn":["9781479903566"]},"author":[{"last_name":"Sprechmann","first_name":"Pablo","full_name":"Sprechmann, Pablo"},{"orcid":"0000-0001-9699-8730","id":"58f3726e-7cba-11ef-ad8b-e6e8cb3904e6","full_name":"Bronstein, Alexander","first_name":"Alexander","last_name":"Bronstein"},{"last_name":"Bronstein","first_name":"Michael","full_name":"Bronstein, Michael"},{"last_name":"Sapiro","first_name":"Guillermo","full_name":"Sapiro, Guillermo"}],"extern":"1","publisher":"IEEE","day":"21","date_created":"2024-10-15T11:20:54Z","month":"10","_id":"18385","status":"public","year":"2013"},{"status":"public","month":"10","_id":"18386","year":"2013","author":[{"full_name":"Sprechmann, Pablo","first_name":"Pablo","last_name":"Sprechmann"},{"last_name":"Bronstein","first_name":"Alexander","full_name":"Bronstein, Alexander","id":"58f3726e-7cba-11ef-ad8b-e6e8cb3904e6","orcid":"0000-0001-9699-8730"},{"last_name":"Morel","first_name":"Jean-Michel","full_name":"Morel, Jean-Michel"},{"full_name":"Sapiro, Guillermo","last_name":"Sapiro","first_name":"Guillermo"}],"extern":"1","publication_identifier":{"eissn":["2379-190X"],"eisbn":["9781479903566"]},"date_created":"2024-10-15T11:20:54Z","day":"21","publisher":"IEEE","publication_status":"published","date_published":"2013-10-21T00:00:00Z","type":"conference","article_processing_charge":"No","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","publication":"2013 IEEE International Conference on Acoustics, Speech and Signal Processing","abstract":[{"lang":"eng","text":"A method for removing impulse noise from audio signals by fusing multiple copies of the same recording is introduced in this paper. The proposed algorithm exploits the fact that while in general multiple copies of a given recording are available, all sharing the same master, most degradations in audio signals are record-dependent. Our method first seeks for the optimal non-rigid alignment of the signals that is robust to the presence of sparse outliers with arbitrary magnitude. Unlike previous approaches, we simultaneously find the optimal alignment of the signals and impulsive degradation. This is obtained via continuous dynamic time warping computed solving an Eikonal equation. We propose to use our approach in the derivative domain, reconstructing the signal by solving an inverse problem that resembles the Poisson image editing technique. The proposed framework is here illustrated and tested in the restoration of old gramophone recordings showing promising results; however, it can be used in other applications where different copies of the signal of interest are available and the degradations are copy-dependent."}],"language":[{"iso":"eng"}],"date_updated":"2024-12-04T13:05:44Z","doi":"10.1109/icassp.2013.6637774","oa_version":"None","citation":{"short":"P.

Therefore, it is frequently used for matching shapes in general, and shapes of handwritten words in Document Image Analysis tasks. As DTW is computationally expensive, efficient algorithms for fast computation are crucial. Retrieving images from large scale datasets using DTW, suffers from the constraint of linear searching of all sample in the datasets. Fast approximation algorithms for image retrieval are mostly based on normed spaces where the triangle inequality holds, which is unfortunately not the case with the DTW metric. In this paper we present a novel approach for fast search of handwritten words within large datasets of shapes. The presented approach is based on the Boost-Map [1] algorithm, for embedding the feature space with the DTW measurement to an euclidean space and use the Local Sensitivity Hashing algorithm (LSH) to rank the k-nearest neighbors of a query image. The algorithm, first, processes and embeds objects of the large data sets to a normed space. Fast approximation of k-nearest neighbors using LSH on the embedding space, generates the top kranked samples which are examined using the real DTW distance to give final accurate results. We demonstrate our method on a database of 45; 800 images of word-parts extracted from the IFN/ENIT database [11] and images collected from 51 different writers.

In this paper, we propose the construction of common approximate eigenbases for multiple shapes using approximate joint diagonalization algorithms, taking as input a set of corresponding functions (e.g. indicator functions of stable regions) on the two shapes.

We show that even with such scarce information, it is possible to establish very accurate correspondence between the shapes by using methods from the field of sparse modeling, being this, the first non-trivial use of sparse models in shape correspondence. We formulate the problem of permuted sparse coding, in which we solve simultaneously for an unknown permutation ordering the regions on two shapes and for an unknown correspondence in functional representation. We also propose a robust variant capable of handling incomplete matches. Numerically, the problem is solved efficiently by alternating the solution of a linear assignment and a sparse coding problem.

After DNA damage, the homotrimeric clamp PCNA, which provides stability and processivity to DNA polymerases and serves as a docking platform for DNA repair enzymes, undergoes modification by the ubiquitin-like molecule SUMO. PCNA SUMOylation helps recruit Srs2 and Elg1 to the replication fork. In the absence of Elg1, both SUMOylated PCNA and Srs2 accumulate at the chromatin fraction, indicating that Elg1 is required for removing SUMOylated PCNA and Srs2 from DNA. Despite this interaction, which suggests that the two proteins work together, double mutants elg1Δ srs2Δ have severely impaired growth as haploids and exhibit synergistic sensitivity to DNA damage and a synergistic increase in gene conversion. In addition, diploid elg1Δ srs2Δ double mutants are dead, which implies that an essential function in the cell requires at least one of the two gene products for survival. To gain information about this essential function, we have carried out a high copy number suppressor screen to search for genes that, when overexpressed, suppress the synthetic lethality between elg1Δ and srs2Δ. We report the identification of 36 such genes, which are enriched for functions related to DNA- and chromatin-binding, chromatin packaging and modification, and mRNA export from the nucleus."}],"date_updated":"2024-12-18T15:30:20Z","type":"journal_article","volume":3,"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","oa":1,"issue":"5","citation":{"short":"I.

The problem is especially hard when the underlying shapes are non-rigid and are given up to a deformation. Partial matching is usually approached by computing local descriptors on a pair of shapes and then establishing a point-wise non-bijective correspondence between the two, taking into account possibly different parts. In this paper, we introduce an alternative correspondence-less approach to matching fragments to an entire shape undergoing a non-rigid deformation. We use region-wise local descriptors and optimize over the integration domains on which the integral descriptors of the two parts match. The problem is regularized using the Mumford-Shah functional.

We use a conceptual semi-distributed model based on elevation bands [Water Evaluation and Planning (WEAP)], frequently used for water management, and a physically oriented, fully distributed model [Topographic Kinematic Wave Approximation and Integration ETH Zurich (TOPKAPI-ETH)] developed for research purposes mainly. We evaluate the ability of the two models to reproduce the key hydrological processes in the basin with emphasis on snow accumulation and melt, streamflow and the relationships between internal processes. Both models are capable of reproducing observed runoff and the evolution of Moderate-resolution Imaging Spectroradiometer snow cover adequately. In spite of WEAP's simple and conceptual approach for modelling snowmelt and its lack of glacier representation and snow gravitational redistribution as well as a proper routing algorithm, this model can reproduce historical data with a similar goodness of fit as the more complex TOPKAPI-ETH. We show that the performance of both models can be improved by using measured precipitation gradients of higher temporal resolution. In contrast to the good performance of the conceptual model for the present climate, however, we demonstrate that the simplifications in WEAP lead to error compensation, which results in different predictions in simulated melt and runoff for a potentially warmer future climate. TOPKAPI-ETH, using a more physical representation of processes, depends less on calibration and thus is less subject to a compensation of errors through different model components. Our results show that data obtained locally in ad hoc short-term field campaigns are needed to complement data extrapolated from long-term records for simulating changes in the water cycle of high-elevation catchments but that these data can only be efficiently used by a model applying a spatially distributed physical representation of hydrological processes."}],"language":[{"iso":"eng"}],"date_updated":"2023-02-24T08:48:40Z","keyword":["Water Science and Technology"],"volume":28,"type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"scopus_import":"1","title":"Comparison of climate change signals in CMIP3 and CMIP5 multi-model ensembles and implications for Central Asian glaciers","quality_controlled":"1","doi":"10.5194/hess-17-3661-2013","oa_version":"Published Version","publication":"Hydrology and Earth System Sciences","article_processing_charge":"No","date_published":"2013-09-01T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.5194/hess-17-3661-2013"}],"publication_status":"published","date_created":"2023-02-20T08:17:05Z","author":[{"first_name":"A.

To estimate future water availability in this region, it is necessary to use climate projections to estimate the future glacier extent and volume. In this study, we evaluate the impact of uncertainty in climate change projections on the future glacier extent in the Amu and Syr Darya river basins. To this end we use the latest climate change projections generated for the upcoming IPCC report (CMIP5) and, for comparison, projections used in the fourth IPCC assessment (CMIP3). With these projections we force a regionalized glacier mass balance model, and estimate changes in the basins' glacier extent as a function of the glacier size distribution in the basins and projected temperature and precipitation. This glacier mass balance model is specifically developed for implementation in large scale hydrological models, where the spatial resolution does not allow for simulating individual glaciers and data scarcity is an issue. Although the CMIP5 ensemble results in greater regional warming than the CMIP3 ensemble and the range in projections for temperature as well as precipitation is wider for the CMIP5 than for the CMIP3, the spread in projections of future glacier extent in Central Asia is similar for both ensembles. This is because differences in temperature rise are small during periods of maximum melt (July–September) while differences in precipitation change are small during the period of maximum accumulation (October–February). However, the model uncertainty due to parameter uncertainty is high, and has roughly the same importance as uncertainty in the climate projections. Uncertainty about the size of the decline in glacier extent remains large, making estimates of future Central Asian glacier evolution and downstream water availability uncertain.","lang":"eng"}],"language":[{"iso":"eng"}],"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","keyword":["General Earth and Planetary Sciences","General Engineering","General Environmental Science"],"volume":17,"type":"journal_article","page":"3661-3677","day":"01","publisher":"Copernicus GmbH","extern":"1","_id":"12638","article_type":"original"},{"date_published":"2013-03-01T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1002/wrcr.20450"}],"publication_status":"published","date_created":"2023-02-20T08:17:12Z","intvolume":"        49","publication_identifier":{"issn":["0043-1397"]},"author":[{"full_name":"Ragettli, S.","last_name":"Ragettli","first_name":"S."},{"full_name":"Pellicciotti, Francesca","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","last_name":"Pellicciotti","first_name":"Francesca"},{"last_name":"Bordoy","first_name":"R.","full_name":"Bordoy, R."},{"full_name":"Immerzeel, W.

In this study the physically oriented, glaciohydrological model TOPKAPI-ETH is used to simulate future changes in snow, glacier, and runoff from the Hunza River Basin in northern Pakistan. Three key sources of model uncertainty in future runoff projections are compared: model parameters, climate projections, and natural climate variability. A novel approach, applicable also to ungauged catchments, is used to determine which model parameters and model components significantly affect the overall model uncertainty. We show that the model is capable of reproducing streamflow and glacier mass balances, but that all analyzed sources of uncertainty significantly affect the reliability of future projections, and that their effect is variable in time and in space. The effect of parametric uncertainty often exceeds the impact of climate uncertainty and natural climate variability, especially in heavily glacierized subcatchments. The results of the uncertainty analysis allow detailed recommendations on network design and the timing and location of field measurements, which could efficiently help to reduce model uncertainty in the future."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"type":"journal_article","volume":49,"keyword":["Water Science and Technology"]},{"scopus_import":"1","title":"Rising river flows throughout the twenty-first century in two Himalayan glacierized watersheds","quality_controlled":"1","oa_version":"None","doi":"10.1038/ngeo1896","publication":"Nature Geoscience","article_processing_charge":"No","date_published":"2013-09-13T00:00:00Z","publication_status":"published","date_created":"2023-02-20T08:17:17Z","author":[{"full_name":"Immerzeel, W.

Here, we use results from the latest ensemble of climate models in combination with a high-resolution glacio-hydrological model to assess the hydrological impact of climate change on two climatically contrasting watersheds in the Greater Himalaya, the Baltoro and Langtang watersheds that drain into the Indus and Ganges rivers, respectively. We show that the largest uncertainty in future runoff is a result of variations in projected precipitation between climate models. In both watersheds, strong, but highly variable, increases in future runoff are projected and, despite the different characteristics of the watersheds, their responses are surprisingly similar. In both cases, glaciers will recede but net glacier melt runoff is on a rising limb at least until 2050. In combination with a positive change in precipitation, water availability during this century is not likely to decline.

It is distributed in a simplistic manner in most glacier melt models by using constant linear lapse rates, which poorly represent the actual spatial and temporal variability of air temperature. In this paper, we test a simple thermodynamic model proposed by Greuell and Böhm in 1998 as an alternative, using a new dataset of air temperature measurements from along the flowline of Haut Glacier d’Arolla, Switzerland. The unmodified model performs little better than assuming a constant linear lapse rate. When modified to allow the ratio of the boundary layer height to the bulk heat transfer coefficient to vary along the flowline, the model matches measured air temperatures better, and a further reduction of the root-mean-square error is obtained, although there is still considerable scope for improvement. The modified model is shown to perform best under conditions favourable to the development of katabatic winds – few clouds, positive ambient air temperature, limited influence of synoptic or valley winds and a long fetch – but its performance is poor under cloudy conditions.","lang":"eng"}],"language":[{"iso":"eng"}],"date_updated":"2023-02-21T10:18:24Z","citation":{"apa":"Petersen, L., Pellicciotti, F., Juszak, I., Carenzo, M., &#38; Brock, B.

In this paper, we test 13 clear-sky parameterizations combined with seven cloud corrections for all-sky atmospheric emissivity at one location on Haut Glacier d'Arolla. We also analyze the four seasons separately and conduct a cross-validation to test the parameters’ robustness. The best parameterization is the one by Dilley and O'Brien, B for clear-sky conditions combined with Unsworth and Monteith cloud correction. This model is also the most robust when tested in cross-validation. When validated at different sites in the southern Alps of Switzerland and north-western Italian Alps, all parameterizations show a substantial decrease in performance, except for one site, thus suggesting that it is important to recalibrate parameterizations of incoming longwave radiation for different locations. We argue that this is due to differences in the structure of the atmosphere at the sites. We also quantify the effect that the incoming longwave radiation parameterizations have on energy-balance melt modeling, and show that recalibration of model parameters is needed. Using parameters from other sites leads to a significant underestimation of melt and to an error that is larger than that associated with using different parameterizations. Once recalibrated, however, the parameters of most models seem to be stable over seasons and years at the location on Haut Glacier d'Arolla."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"volume":118,"type":"journal_article","keyword":["Space and Planetary Science","Earth and Planetary Sciences (miscellaneous)","Atmospheric Science","Geophysics"],"page":"3066-3084","day":"27","publisher":"American Geophysical Union","extern":"1","_id":"12643","article_type":"original","scopus_import":"1","quality_controlled":"1","title":"A comparison of parameterizations of incoming longwave radiation over melting glaciers: Model robustness and seasonal variability","oa_version":"Published Version","doi":"10.1002/jgrd.50277","publication":"Journal of Geophysical Research: Atmospheres","article_processing_charge":"No","date_published":"2013-04-27T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1002/jgrd.50277"}],"publication_status":"published","date_created":"2023-02-20T08:17:34Z","intvolume":"       118","publication_identifier":{"issn":["2169-897X"]},"author":[{"first_name":"I.","last_name":"Juszak","full_name":"Juszak, I."},{"first_name":"Francesca","last_name":"Pellicciotti","full_name":"Pellicciotti, Francesca","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70"}],"year":"2013","month":"04","status":"public"},{"volume":33,"type":"journal_article","abstract":[{"lang":"eng","text":"When confronted with a large-field stimulus rotating around the vertical body axis, flies display a following behavior called &quot;optomotor response.&quot; As neural control elements, the large tangential horizontal system (HS) cells of the lobula plate have been prime candidates for long.

To minimize interference of the optical activation of channelrhodopsin-2 with the visual perception of the flies, we used a bistable variant called ChR2-C128S. By applying pulses of blue and yellow light, we first demonstrate electrophysiologically that lobula plate tangential cells can be activated and deactivated repeatedly with no evident change in depolarization strength over trials.

However, how these pathways are functionally specialized remains controversial. One study (Eichner et al., 2011) proposed that the L1-pathway evaluates only sequences of brightness increments (ON-ON), while the L2-pathway processes exclusively brightness decrements (OFF-OFF). Another study (Clark et al., 2011) proposed that each of the two pathways evaluates both ON-ON and OFF-OFF sequences. To decide between these alternatives, we recorded from motionsensitive neurons in flies in which the output from either L1 or L2 was genetically blocked. We found that blocking L1 abolishes ON-ON responses but leaves OFF-OFF responses intact. The opposite was true, when the output from L2 was blocked. We conclude that the L1 and L2 pathways are functionally specialized to detect ON-ON and OFF-OFF sequences, respectively.","lang":"eng"}],"page":"902 - 905","publication_status":"published","date_published":"2013-01-16T00:00:00Z","year":"2013","month":"01","_id":"1305","status":"public","day":"16","publisher":"Society for Neuroscience","date_created":"2018-12-11T11:51:16Z","publist_id":"5968","intvolume":"        33","author":[{"last_name":"Jösch","first_name":"Maximilian A","full_name":"Maximilian Jösch","id":"2BD278E6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3937-1330"},{"last_name":"Weber","first_name":"Franz","full_name":"Weber, Franz"},{"full_name":"Eichner, Hubert","last_name":"Eichner","first_name":"Hubert"},{"first_name":"Alexander","last_name":"Borst","full_name":"Borst, Alexander"}],"extern":1},{"publist_id":"5962","intvolume":"        38","author":[{"last_name":"Fischer","first_name":"Julian L","full_name":"Julian Fischer","id":"2C12A0B0-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0479-558X"}],"extern":1,"day":"01","publisher":"Taylor & Francis","date_created":"2018-12-11T11:51:17Z","_id":"1307","month":"11","status":"public","year":"2013","date_published":"2013-11-01T00:00:00Z","publication_status":"published","page":"2004 - 2047","abstract":[{"text":"We prove uniqueness of solutions of the DLSS equation in a class of sufficiently regular functions.
