Abstract
An adaptive domain pool scheme for fractal image compression is proposed in this paper. This scheme adaptively selects domain pool for each range block based on the range’s location, so there is a more effective and smaller domain library for each range. This technique results in the decrease of the computational load and the bits needed to store the domain location. The experimental results on standard images show that the proposed method yields a far better rate-distortion performance and has a far lower computational load. And finally we also perform the comparison of this method against the block partition (domain pool scheme) method.Â
