Abstract

"In this paper we propose a new technique for compressing stereo images using multiscale recunent patterns. The idea consists on representing blocks of the image using variable- sized elements of a dictionary. More specifically, blocks of the image ave represented by contracted, expanded or displaced elements of the dictionary. The patterns learned along the reference image process are included in the dictionary. The novelty of this work is the absence of the disparity map in the stereo image coding process. That is, the burden of its calculation, the pre- and post-processing phases, the generation of the error images, as well as their coding and transmission ave not necessary. In brief, the proposed method cuts off the load of the whole disparity estimation process yet presenting high-quality results at the decoder end."
