In this paper, we consider sparse representations of multidimensional signals (tensors) by generalizing the one-dimensional case (vectors). A new greedy algorithm, namely the Tensor-OMP algorithm, is proposed to compute a ...

Stereo matching (or stereo vision) is a field of computer vision that has been getting at- tention over the last decades, because of its wide range of applications and versatility. It addresses the problem of 3D ...

Block matching (BM) motion estimation plays a very important role in video coding. In a BM approach, image frames in a video sequence are divided into blocks. For each block in the current frame, the best matching block ...
