| Outline of Final Research Achievements |
Sparse representation is one of the hottest topics in signal processing, and approximates a given signal by a linear combination of less numbers of basis vectors. In this research, we applied sparse representation to multi-view video coding to achieve higher coding performance than the conventional video coding framework used in MPEGs, and tried faster implementation using multi-cores in GPU and CPU. Research results show the effectiveness of sparse representation in video coding, and also tell us that the proposed parallel processing is about 2.7 times faster than the execution using CPU. This research includes accurate estimation of Fundamental matrix to obtain geometric information of objects from multi-view images.
