Research on Medical Image Registration Comparison Based on Algorithm Stitching Optimization

With the development of medical technology, the problem of medical image registration is becoming more and more prominent. Two CT images were performed on the same patient. During the time difference between the two images, different degrees of lesions may occur in the detected part. However, due to the softness of human tissue and the automatic zooming of the image when the equipment finally outputs, the image size and rotation angle of the two outputs lose contrast.
