A new alogrithm on lifting multiwavelst transform for image fusion

Abstract

There are many methods for image fusion now. However, Multi-wavelet is attached importance to its superiority on theory and its potential on applications. Lifting scheme is not only a fast algorithm of existing wavelet transforms, but also a tool to produce new wavelet transforms. According to the characteristic of the lifting scheme and multi-wavelet transform, a new lifting scheme for multi-wavelet transforms was presented in this paper, and it was applied to image fusion. Better results were achieved.
