Image compression using wavelet packets
Deepak Kumar Gupta, Samata Mutha · 2004
Algorithms based on wavelets have been shown to work well in image compression. Advances in wavelet transform and quantisation methods have produced the algorithm capable of surpassing the existing image compression standards like the joint photographic experts group (JPEG algorithm). This paper presents new wavelet packets algorithms for image compressions. Extensive experiment results prove that our techniques exhibit performance equal to, or in several cases superior to, the current wavelet filters.
