A Way of Image Fusion Based on Wavelet Transform

摘要

In this paper a way of medical image fusion based on wavelet theory is introduced. Medical image fusion have three steps, they are image processing, image registration and image fusion. In the paper, image processing get across multi resolution characteristics of wavelet to denoise, image registration pass the wavelet analysis to gain biggish change point and receive image edge to achieve quick and nice superposable, image fusion use disassumble image to different frequency sub band to save all information to have a perfect fusion. Simulation experiment proved it has advantages of simply calculation, fast superposition and perfect fusion in medical image fusion. It is a direction of medical reacher and clinic iatrology.
