Improved Algorithm of Region Growing Based on Weak Edge Reject

An improved algorithm of region growing based on weak edge reject is proposed in this paper,whichintroduces the discriminant formula of similarity about main structure between two images. On the image-processingstage,the small texture and weak edge of the same goal are rejected while the main structure remains there. It isindicated from the simulation experiment that the algorithm has the capability to avoid the possibility that the samegoal is divided into several small regions when the goal segmentation through the traditional region-growing algorithmis conducted,thus the veracity of segmentation and extraction can be further enhanced.
