An Excellent Wavelet for Image and Video Compression

Abstract

Abstract.A specific wavelet--W97 has studied systematically. It has shown that the W 97 has good mathematical properties, and its lifting coefficients are very suitable for software and ASIC implementation. Lots of experiments have shown W97 precedes CDF97 on compression performance , and W 97's computation complexity is obviously lower than CDF97's. So, W 97 is an excellent wavelet for image and video compression technique.
