Realization and Improvement of Low-Rate Video Coding Standard-H.26L

An improved algrothm based on H.26L video coding standard is proposed. Superior serching method and bi-directional interpolation method are adopted to enhence image reconstruction quality. By make using of MB spatial relativity, the quantified block can be judged whether it can be combined before coding. Experimental results shows that the proposed algorithm is very efficient in terms of the image compressibility.
