| Abstract: | In this paper, a video coding solution using Gabor Based regional matching pursuit is presented to overcome the block edge artifacts and noticeable distortion. The solution improved the performance of baseline algorithm in Zakhor by proposing a new construction of Gabor matching pursuit overcompleted basis set and a new control of regional matching pursuit iterative convergence. The result is compared to H.263 DCT based coding including 10 kb/s and 24 kb/s. |
