Abstract

Because the operational speed of the traditional image compression based on Mallat algorithm is slow, and auxiliary Storage space is occupied, image compressed method based on lifting wavelet transform is proposed, in order to realize its versatility, flexibility and high efficient. Experiments show that the lifting wavelet transform, is easy to realize integer wavelet transform can be used for lossless compression, and has higher compression ratio.
