Medical image fusion techniques can fuse medical images from different morphologies to make the medical diagnosis more reliable and accurate, which play an increasingly important role in many clinical applications.To obtain a fused image with high visual quality and nightstick twm-850xl clear structure details, this paper proposes a convolutional neural network (CNN) based medical image fusion algorithm.The proposed algorithm uses the trained Siamese convolutional network to fuse the pixel activity information of source images to realize the generation of weight map.Meanwhile, a contrast pyramid is implemented to google pixel 7 freedom decompose the source image.According to different spatial frequency bands and a weighted fusion operator, source images are integrated.

The results of comparative experiments show that the proposed fusion algorithm can effectively preserve the detailed structure information of source images and achieve good human visual effects.
