A New Method of Bio-medical Image Fusion with Multi-scale Edge

摘要

Discrete Wavelet Transform (DWT) provides a fast, local, sparse multi-resolution analysis of signals. It can reconstruct high quality images. By comparison, we find the shortcoming of current bio-medical image fusion method, and a new method for bio-medical image fusion based on combination of graph formed by its multi-scale edge of DWT has been presented in this paper. By many experiments and application, the correctness of our method has been tested. This method is valid for application of high belief degree of image process fields for bio-medical decision and analysis.
