Abstract

Based on the directionality of images and combining the direction information with multiple resolution analysis, an image enhancement idea via fusion based on directional filter banks is presented in this paper. Combining with LP analysis further, an image fusion method based on LPDFB is given in the paper. Using the experiments to compare the results, they prove its feasibility and validity.
