Abstract

Abstract

Wavelet transform is widely used in image fusion with its good features. But the algorithm based on Mallat has a major disadvantage for it contains interpolation and decimation. The new Trous algorithm, formed by convolving with an increasingly dilated Wavelet function, doesn't have the procedure of interpolation and decimation, and so it can solve the problem. This article firstly introduce representation of information and algorithms and applications of fusion and emphasize the algorithm based on Trous Wavelet transform. In the end, it indicate that visual effects, average gradient and standard deviation could implement the image quality evaluations after fusion. The results show that the images after fusion can keep the information of the raw image.
