【Abstract】 The theory of wavelet transform on image processing is introduced and the block coding algorithm is also discussed. Taking account of the optical character of eyes and the relativity of the sub-block, fractal coding is applied to compress image effectively. The result of simulation shows that the compressing ratio of this method is superior than that of other conventional methods, and so is the image decompressing quality.更多还原
