Abstract
En 中文
A fractal coder partitions an image into blocks that are coded via self-references to other parts of the image itself. In this paper we present a fractal coder that derives highly image-adaptive partitions and corresponding fractal codes in a time-efficient manner using a region-merging approach. The proposed merging strategy leads to improved rate-distortion performance compared to previously reported pure fractal coders, and it is faster than other state-of-the-art fractal coding methods.
