We address the symmetric flip problem that is inherent to multiresolution isometric shape matching algorithms. To this effect, we extend our previous work which handles the dense isometric correspondence problem in the original 3D Euclidean space via coarse-to-fine combinatorial matching. The key idea is based on keeping track of all optimal solutions, which may be more than one due to symmetry...

We present a novel method for tracking objects by combining density matching with shape priors. Density matching is a tracking method which operates by maximizing the Bhattacharyya similarity measure between the photometric distribution from an estimated image region and a model photometric distribution. Such trackers can be expressed as PDE-based curve evolutions, which can be implemented usin...

-This paper presents a novel potential-based approach for recognizing the shape of a twodimensional (2D) reKion by identifying the best match from a selected group of shape templates. The proposed model assumes that the border of every 2D region is uniformly charged. An initially small shape template placed inside a shape sample will experience the repulsive force and torque arising from the po...

We present a novel approach to the problem of establishing the best match between an open contour and a part of a closed contour. At the heart of the proposed scheme lies a novel shape descriptor that also permits the quantification of local scale. Shape descriptors are computed along open or closed contours in a spatially non-uniform manner. The resulting ordered collections of shape descripto...

Sound-shape associations involving consistent matching of nonsense words such as 'bouba' and 'kiki' with curved and angular shapes, respectively, have been replicated in several studies. The purpose of the current study was to examine the robustness of previously noted sound-shape associations when shape variations (angular and curvy) are embedded in schematic expressions of emotions (sad and h...

Because of recent advances in graphics hardand software, both the production and use of 3D models are increasing at a rapid pace. As a result, a large number of 3D models have become available on the web, and new research is being done on 3D model retrieval methods. Query and retrieval can be done solely based on associated text, as in image retrieval, for example (e.g. Google Image Search [15]...

We present an efficient and unconditionally stable method which allows the deformation of very complex stiff cloth models in real-time. This method is based on a shape matching approach which uses edges and triangles as 1D and 2D regions to simulate stretching and shearing resistance. Previous shape matching approaches require large overlapping regions to simulate stiff materials. This unfortun...

In this paper we define a multi-scale distance between shapes based on geodesics in the shape space. The proposed distance, robust to outliers, uses shape matching to compare shapes locally. The multi-scale analysis is introduced in order to address local and global variabilities. The resulting similarity measure is invariant to translation, rotation and scaling independently of constraints or ...
