[{"abstract":[{"text":"Analysis of intrinsic symmetries of non-rigid and articulated shapes is an important problem in pattern recognition with numerous applications ranging from medicine to computational aesthetics. Considering articulated planar shapes as closed curves, we show how to represent their extrinsic and intrinsic symmetries as self-similarities of local descriptor sequences, which in turn have simple interpretation in the frequency domain. The problem of symmetry detection and analysis thus boils down to analysis of descriptor sequence patterns. For that purpose, we show two efficient computational methods: one based on Fourier analysis, and another on dynamic programming.","lang":"eng"}],"page":"665–676","status":"public","oa_version":"None","conference":{"name":"Third International Conference on Scale Space and Variational Methods in Computer Vision","start_date":"2012-05-29","location":"Ein-Gedi, Israel","end_date":"2012-06-02"},"article_processing_charge":"No","year":"2012","alternative_title":["LNCS"],"publication_status":"published","citation":{"apa":"Hooda, A., Bronstein, M.

In some applications, it is possible to design an optimal filter. A classical example is the Wiener filter that achieves a minimum mean squared error estimate for signal denoising. Here, we adopt similar concepts to construct optimal diffusion geometric shape descriptors. The analogy of Fourier basis are the eigenfunctions of the Laplace-Beltrami operator, in which many geometric constructions such as diffusion metrics, can be represented. By designing a filter of the Laplace-Beltrami eigenvalues, it is theoretically possible to achieve invariance to different shape transformations, like scaling. Given a set of shape classes with different transformations, we learn the optimal filter by minimizing the ratio between knowingly similar and knowingly dissimilar diffusion distances it induces. The output of the proposed framework is a filter that is optimally tuned to handle transformations that characterize the training set.","lang":"eng"}],"page":"689-700","author":[{"full_name":"Aflalo, Yonathan","last_name":"Aflalo","first_name":"Yonathan"},{"full_name":"Bronstein, Alexander","last_name":"Bronstein","first_name":"Alexander","orcid":"0000-0001-9699-8730","id":"58f3726e-7cba-11ef-ad8b-e6e8cb3904e6"},{"full_name":"Bronstein, Michael M.","last_name":"Bronstein","first_name":"Michael M."},{"first_name":"Ron","last_name":"Kimmel","full_name":"Kimmel, Ron"}],"language":[{"iso":"eng"}],"publication_identifier":{"isbn":["9783642247842"],"eissn":["1611-3349","9783642247859"],"issn":["0302-9743"]},"day":"09","publication":"3rd International Conference on Scale Space and Variational Methods in Computer Vision","publication_status":"published","citation":{"chicago":"Aflalo, Yonathan, Alex M.

It has been shown that the eigenfunctions of the Laplace-Beltrami operator (manifold harmonics) of a surface play the role of the Fourier basis in the Euclidean space; it is thus possible to formulate signal analysis and synthesis in the manifold harmonics basis. In particular, geometry filtering can be carried out in the manifold harmonics domain by decomposing the embedding coordinates of the shape in this basis. However, since the basis functions depend on the shape itself, such filtering is valid only for weak (near all-pass) filters, and produces severe artifacts otherwise. In this paper, we analyze this problem and propose the fractional filtering approach, wherein we apply iteratively weak fractional powers of the filter, followed by the update of the basis functions. Experimental results show that such a process produces more plausible and meaningful results.","lang":"eng"}],"alternative_title":["LNCS"],"type":"conference","issue":"Part 1","publisher":"Springer Nature","date_created":"2024-10-15T11:20:54Z","scopus_import":"1","quality_controlled":"1","date_published":"2012-08-31T00:00:00Z","doi":"10.1007/978-3-642-33863-2_9","extern":"1","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87"},{"_id":"18350","type":"conference","date_updated":"2025-01-16T10:12:48Z","quality_controlled":"1","date_published":"2012-09-01T00:00:00Z","publisher":"Springer Nature","date_created":"2024-10-15T11:20:54Z","scopus_import":"1","doi":"10.1007/978-3-642-34091-8_8","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","extern":"1","volume":7474,"month":"09","title":"Equi-affine invariant geometries of articulated objects","intvolume":"      7474","publication_status":"published","citation":{"apa":"Raviv, D., Bronstein, A.

Recent works have successfully extended the maximally stable extremal region (MSER) detection algorithm to surfaces. In many applications, however, a volumetric shape model is more appropriate, and modeling shape deformations as approximate isometries of the volume of an object, rather than its boundary, better captures natural behavior of non-rigid deformations. In this paper, we formulate a diffusion-geometric framework for volumetric stable component detection and description in deformable shapes. An evaluation of our method on the SHREC'11 feature detection benchmark and SCAPE human body scans shows its potential as a source of high-quality features.

To deal with orientation ambiguity, we exploit properties of the Fourier transform. Our charting method is intrinsic, i.e., invariant to isometric shape transformations. The resulting descriptor is a meta-descriptor that can be applied to any photometric or geometric property field defined on the shape, in particular, we can leverage recent developments in intrinsic shape analysis and construct ISC based on state-of-the-art dense shape descriptors such as heat kernel signatures.

Feature descriptors can be designed to be invariant to certain classes of photometric and geometric transformations, in particular, affine and intensity scale transformations. However, real transformations that an image can undergo can only be approximately modeled in this way, and thus most descriptors are only approximately invariant in practice. Second, descriptors are usually high dimensional (e.g., SIFT is represented as a 128--dimensional vector). In large-scale retrieval and matching problems, this can pose challenges in storing and retrieving descriptor data. We map the descriptor vectors into the Hamming space in which the Hamming metric is used to compare the resulting representations. This way, we reduce the size of the descriptors by representing them as short binary strings and learn descriptor invariance from examples. We show extensive experimental validation, demonstrating the advantage of the proposed approach."}],"pmid":1,"date_updated":"2024-11-12T08:34:48Z","_id":"18412","title":"LDAHash: Improved matching with smaller descriptors","intvolume":"        34","month":"01","volume":34,"external_id":{"pmid":["21576750 "]},"author":[{"first_name":"C.","last_name":"Strecha","full_name":"Strecha, C."},{"last_name":"Bronstein","full_name":"Bronstein, Alexander","id":"58f3726e-7cba-11ef-ad8b-e6e8cb3904e6","orcid":"0000-0001-9699-8730","first_name":"Alexander"},{"full_name":"Bronstein, M.

However, detecting spontaneous PSCs in vitro and in vivo has been challenging, because of the small amplitude, the variable kinetics, and the undefined time of generation of these events. Here, we describe a, to our knowledge, new method for detecting spontaneous synaptic events by deconvolution, using a template that approximates the average time course of spontaneous PSCs. A recorded PSC trace is deconvolved from the template, resulting in a series of delta-like functions. The maxima of these delta-like events are reliably detected, revealing the precise onset times of the spontaneous PSCs. Among all detection methods, the deconvolution-based method has a unique temporal resolution, allowing the detection of individual events in high-frequency bursts. Furthermore, the deconvolution-based method has a high amplitude resolution, because deconvolution can substantially increase the signal/noise ratio. When tested against previously published methods using experimental data, the deconvolution-based method was superior for spontaneous PSCs recorded in vivo. Using the high-resolution deconvolution-based detection algorithm, we show that the frequency of spontaneous excitatory postsynaptic currents in dentate gyrus granule cells is 4.5 times higher in vivo than in vitro."}],"main_file_link":[{"url":"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3471482/","open_access":"1"}],"isi":1,"day":"03","title":"A deconvolution based method with high sensitivity and temporal resolution for detection of spontaneous synaptic currents in vitro and in vivo","intvolume":"       103","oa":1,"volume":103,"month":"10","external_id":{"isi":["000309571400005"],"pmid":["23062335"]},"pmid":1,"acknowledgement":"This work was supported by the Deutsche Forschungsgemeinschaft (TR3/B10) and a European Research Council Advanced grant to P.J.\r\nWe thank H.

It has long been proposed that the position and polarity of cells at the 16- to 32-cell stage embryo influence their decision to either give rise to the pluripotent cell lineage that eventually contributes to the inner cell mass (ICM), comprising the primitive endoderm (PE) and the epiblast (EPI), or the extra-embryonic trophectoderm (TE) surrounding the blastocoel. The positioning of cells in the embryo at this developmental stage could largely be the result of random events, making this a stochastic model of cell lineage allocation. Contrary to such a stochastic model, some studies have detected putative differences in the lineage potential of individual blastomeres before compaction, indicating that the first cell fate decisions may occur as early as at the 4-cell stage. Using a non-invasive, quantitative in vivo imaging assay to study the kinetic behavior of Oct4 (also known as POU5F1), a key transcription factor (TF) controlling pre-implantation development in the mouse embryo, 3-5 a recent study identifies Oct4 kinetics as a predictive measure of cell lineage patterning in the early mouse embryo. 6 Here, we discuss the implications of such molecular heterogeneities in early development and offer potential avenues toward a mechanistic understanding of these observations, contributing to the resolution of the controversy of developmental cell lineage allocation.","lang":"eng"}]},{"day":"01","alternative_title":["LNCS"],"das_tickbox":"1","status":"public","abstract":[{"text":"Leakage resilient cryptography attempts to incorporate side-channel leakage into the black-box security model and designs cryptographic schemes that are provably secure within it. Informally, a scheme is leakage-resilient if it remains secure even if an adversary learns a bounded amount of arbitrary information about the schemes internal state. Unfortunately, most leakage resilient schemes are unnecessarily complicated in order to achieve strong provable security guarantees. As advocated by Yu et al. [CCS’10], this mostly is an artefact of the security proof and in practice much simpler construction may already suffice to protect against realistic side-channel attacks. In this paper, we show that indeed for simpler constructions leakage-resilience can be obtained when we aim for relaxed security notions where the leakage-functions and/or the inputs to the primitive are chosen non-adaptively. For example, we show that a three round Feistel network instantiated with a leakage resilient PRF yields a leakage resilient PRP if the inputs are chosen non-adaptively (This complements the result of Dodis and Pietrzak [CRYPTO’10] who show that if a adaptive queries are allowed, a superlogarithmic number of rounds is necessary.) We also show that a minor variation of the classical GGM construction gives a leakage resilient PRF if both, the leakage-function and the inputs, are chosen non-adaptively.","lang":"eng"}],"main_file_link":[{"url":"http://www.iacr.org/archive/ches2012/74280211/74280211.pdf","open_access":"1"}],"scopus_import":"1","publisher":"Springer","date_created":"2018-12-11T11:55:25Z","date_published":"2012-09-01T00:00:00Z","quality_controlled":"1","type":"conference","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.1007/978-3-642-33027-8_13","publist_id":"5003","department":[{"_id":"KrPi"}],"author":[{"full_name":"Faust, Sebastian","last_name":"Faust","first_name":"Sebastian"},{"first_name":"Krzysztof Z","orcid":"0000-0002-9139-1654","id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","full_name":"Pietrzak, Krzysztof Z","last_name":"Pietrzak"},{"first_name":"Joachim","id":"7BE863D4-E9CF-11E9-9EDB-90527418172C","full_name":"Schipper, Joachim","last_name":"Schipper"}],"language":[{"iso":"eng"}],"publication":"Conference proceedings CHES 2012","citation":{"apa":"Faust, S., Pietrzak, K.

In this paper, we study conditions that need to be imposed on interface models in order to enforce independent implementability with respect to conjunction. We focus on multiple viewpoint specifications and propose a new compatibility criterion between two interfaces, which we call orthogonality.
