A Medical Image Fusion Algorithm Based on Lifting Wavelet Transform

Image fusion is a technigue that integrates the information of multiple images into one image, which makes the fused image more accurate, more comprehensive and reliable. In order to improve the traditional medical image fusion algorithms which often cause details loss, the source medical images are decomposed by way of lifting wavelet, and the high-low frequency weight are utilized according to different fusion rules. Finally the target image is obtained through inverse wavelet transform. The simulation result shows that the algorithm is feasible and effective.
