Liao Wei-zhi · Microelectronics & Computer · 2007
This paper introduced the image fractal compression technical basic theories based on Iterated function system. It makes use of self-similarity feature from an original image and its relative gradient image. The method of adaptive quad-tree partitioning is adopted. We give a parallel algorithm of relative gradient-based adaptive image fractal compression.The algorithmic complexity analyzed indicates that the method raised compression ratio of image fractal compression, compute quantity is little, and the efficiency is higher.
