Mengyu Zhu, Yuliang Yang · 2009
An improved Simulated Annealing algorithm in conjunction with GLA algorithm has been proposed in this paper. Using SA algorithm and new distortion measure, our new algorithm can avoid the GLA algorithm's defect in that is sensitive to the original codebook and is easy to fall into the locally optimal solution during the searching. The experiment results indicate that the improved algorithm can efficiently eliminate the sensibility to the original codebook, and improve performance for searching ability and subjective quality of decoding image.
