Research highlights ► Approximate the medial axis of a polyhedron with a dense set of medial points. ► Partition this set of medial points into medial sheets. ► Estimate boundary curvature of the solid from the approximation to the medial axis. ► Show how the number of medial sheets can...
Research highlights ► Learning concise 3D shape representations for object categories. ► Novel probabilistic solutions to the shape-from-silhouettes problem. ► Uncertainty measurements of single and sparse-view reconstruction.
Research highlights ► Local shape descriptor selection is expressed as an optimization problem. ► A generalized platform subsumes a large class of range data point matching methods. ► The descriptors are tuned to the geometry of specific models via feature selection. ► Object recognition...
Research highlights ► A carefully designed computer vision system reconstructs human faces from video data. ► 2D mesh tracking naturally handles movements in opposite directions (eyes, lips). ► Surfel fitting provides 3D constraints to track a 3D face model. ► Deformation transfer...
Research highlights ► Finite impulse response filters can be embedded in illumination. ► In projector–camera systems each sensor pixel footprint can be computed. ► Subpixel filtering of non-planar surface textures using dense light fields. ► Optically-based geometry clipping algorithm...
Research highlights ► Registering range images of Lambertian objects using albedo. ► Matching corresponding points using local distribution of albedo. ► Modeling local distribution of albedo using adaptive regions. ► Eliminating mismatches using the rigidity constraint of surfaces.
Research highlights ► Measure 3D shape similarity by matching a medial axis (MA) based representation. ► Represent shape similarity as the minimum extent of deformation guided by the MS. ► Model shape deformation path as transitions of the MS associated with a cost. ► Define compatibility...
Research highlights ► A single viewpoint capture is used to create a complete model of a symmetric object. ► Global symmetry is detected from a captured fragment of the complete object. ► Zippering symmetric fragments do not require the fragments to be aligned via ICP. ► Algorithms are...
Research highlights ► Surfel representation for real-time modeling. ► Surfel visibility for registration robustness. ► Combined texture and geometry registration to handle a wide range of objects. ► Efficient online loop closure using high level topology graph.
