Multi-band Vector Wavelet Transformation based Multi-Focus Image Fusion Algorithm

摘要

Multi-focus image fusion is one of the important embranchments of image fusion. It has been widely used in target identification, remote sensing image processing and so on. In this paper, a new multi-focus image fusion method based on multi-band vector wavelet is presented. Furthermore, some post processing is done in this paper, in which anisotropic diffusion arithmetic based on partial differential equations is used. As for the fusion image, the blocking effects which usually existed in the results are eliminated by using wavelet based image fusion method. To test and evaluate the proposed method, it is applied to a case study to demonstrate its performance in image fusion. Comparisons of experimental results by using several methods demonstrated the effectiveness of our proposed methods.
