Image segmentation is the base of image 3D reconstruction. It is a critical step in image processing. Threshold segmentation is a simple and important method in grayscale image segmentation. Maximum entropy method is a common threshold segmentation method. This method only utilizes gray information. In order to adequately utilize spatial information of greyscale image, an improved 2D entropy segmentation...
Medical image segmentation is the basis of medical image three-dimensional reconstruction. The accuracy of image segmentation directly affects the results of image 3D reconstruction. According to the grayscale feature of different tissues in CT image and the image symmetry, a new algorithm of obtaining tissue contour lines is put forward. Using edge detection with specific threshold and improved contour...
