We present an efficient algorithm for non-rigid registration of two partially overlapping 3D surfaces in which a target surface is a deformed instance of a source surface. The algorithm is implemented in two main phases. In the first phase, the robust algorithm that is used is based on a probability density estimation to find reliable correspondences(More)
A novel algorithm is proposed for extracting sharp features automatically and at optimal scale from point clouds. First, the vector between a given point and the centroid of its neighborhood at a given scale is projected on the normal at this point. This projection is called the 'projected distance' at this point. The projected distance and surface normal(More)
A novel algorithm is proposed for extracting sharp features automatically from scanned 3D data of man-made CAD-like objects. The input of our method consists of a mesh or an unstructured point cloud that is captured on the object surface. First, the vector between a given point and the centroid of its neighborhood at a given scale is projected on the normal(More)
In this paper a novel cyclic interface for searching through a song database is proposed. The method, which merges multiple audio streams on a server and broadcasts only a single merged stream, allows the user to hear different parts of each audio stream by cycling through all available streams. Experimental results on 21 users illustrate that the proposed(More)
