However, despite the high-resolution quality of the reconstruction approaches available, current methods are unable to capture one of the most important regions of the face - the eye region. In this work we present the first method for detailed spatio-temporal reconstruction of eyelids. Tracking and reconstructing eyelids is extremely challenging, as this region exhibits very complex and unique skin deformation where skin is folded under while opening the eye. Furthermore, eyelids are often only partially visible and obstructed due to selfocclusion and eyelashes. Our approach is to combine a geometric deformation model with image data, leveraging multi-view stereo, optical flow, contour tracking and wrinkle detection from local skin appearance. Our deformation model serves as a prior that enables reconstruction of eyelids even under strong self-occlusions caused by rolling and folding skin as the eye opens and closes. The output is a person-specific, time-varying eyelid reconstruction with anatomically plausible deformations. Our high-resolution detailed eyelids couple naturally with current facial performance capture approaches. As a result, our method can largely increase the fidelity of facial capture and the creation of digital doubles.","lang":"eng"}],"type":"conference","citation":{"ama":"Bermano A, Beeler T, Kozlov Y, Bradley D, Bickel B, Gross M.

Traditionally, aerodynamics are examined through elaborate wind tunnel experiments or expensive fluid dynamics computations, and are only measured for a small number of discrete wind directions. OmniAD allows the evaluation of aerodynamic forces, such as drag and lift, for any incoming wind direction using a novel representation based on spherical harmonics. Our datadriven technique acquires the aerodynamic properties of an object simply by capturing its falling motion using a single camera. Once model parameters are estimated, OmniAD enables realistic realtime simulation of rigid bodies, such as the tumbling and gliding of leaves, without simulating the surrounding air. In addition, we propose an intuitive user interface based on OmniAD to interactively design three-dimensional kites that actually fly. Various nontraditional kites were designed to demonstrate the physical validity of our model.","lang":"eng"}],"type":"conference","quality_controlled":"1","language":[{"iso":"eng"}],"status":"public","article_processing_charge":"No","author":[{"last_name":"Martin","full_name":"Martin, Tobias","first_name":"Tobias"},{"first_name":"Nobuyuki","last_name":"Umetani","full_name":"Umetani, Nobuyuki"},{"first_name":"Bernd","orcid":"0000-0001-6511-9385","full_name":"Bickel, Bernd","last_name":"Bickel","id":"49876194-F248-11E8-B48F-1D18A9856A87"}],"title":"OmniAD: Data-driven omni-directional aerodynamics","date_updated":"2025-09-23T09:42:49Z","oa_version":"None","publist_id":"5532","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","isi":1,"article_number":"113","year":"2015","doi":"10.1145/2766919","day":"27","date_published":"2015-07-27T00:00:00Z","intvolume":"        34"},{"department":[{"_id":"BeBi"}],"volume":34,"publisher":"ACM","quality_controlled":"1","type":"conference","abstract":[{"text":"We present a computational tool for fabrication-oriented design of flexible rod meshes.

While significant progress has occurred over the last two decades, no single survey currently exists that discusses the similarities, differences, and practical considerations of the available appearance capture techniques as applied to human faces. A central difficulty of facial appearance capture is the way light interacts with skin-which has a complex multi-layered structure-and the interactions that occur below the skin surface can, by definition, only be observed indirectly. In this report, we distinguish between two broad strategies for dealing with this complexity. &quot;Image-based methods&quot; try to exhaustively capture the exact face appearance under different lighting and viewing conditions, and then render the face through weighted image combinations. &quot;Parametric methods&quot; instead fit the captured reflectance data to some parametric appearance model used during rendering, allowing for a more lightweight and flexible representation but at the cost of potentially increased rendering complexity or inexact reproduction. The goal of this report is to provide an overview that can guide practitioners and researchers in assessing the tradeoffs between current approaches and identifying directions for future advances in facial appearance capture."}],"type":"journal_article","citation":{"short":"O.
