Luo Li · 2006
Based on the thorough study of key algorithms of constrained distortion video codec, several optimization methods are proposed in this paper to enhance the coding speed and promote the applications of video coding in actual practice. Entropy theory and image compression theory adopted, the model selection on coding algorithm of the new standards of video coding which named H.264 is proposed based on constrained distortion feature mathematical model and lagrange multipliers. For achieving the higher compression ratio, the better picture quality and quicker coding speed, we probe into the ultimate theory on source coding. In the last of this paper, a total performance test is performed on the M61e(JUT Test Model)system test model with the method of coding model selection we proposed.
