摘要：

This paper describes an algorithm that combines region growing and edge detection to segment out an object in the image. The algorithm starts with the gradient image and an initial patch located inside the boundary of the region. Then, pixels adjacent to the region are iteratively merged with it. During this process two criteria are used to control the growth. The first one compares the image data with the region model. The second criterion uses gradient information to detect the optimal region boundary and stop the growth.
