Abstract
In this paper, cosine-modulated filter banks are introduced into fract al image coding to remove the block effects which exist in conventiona l block-based fractal image compression both in spatial and frequency domains. The proposed method offers not only an efficient solution to such block effects but also better objective performances. Compared wi th the fractal image compression methods based on discrete cosine tran sform, about 1dB SNR gains can be achieved.
