The study of image edge segmentation based on Hough transform

摘要

In this paper, a new algorithm is proposed to segment medical images to extract the contour of the objects. First, do edge segmentation to the image region with Prewitt operator. And then use Hough transformation to detect the incontinuous points in curve and link the edges. An accurate edge of the organ or tissue of human can be extracted through this method. Based on this, more information can be used to build the models for the organs or tissues.
