In order to segment and extract the target fast and accurately,a new fast segmentation algorithm fully based on edge information is proposed.Firstly the edge detected by Canny operator is thinned by the non-maxima suppression method based on the neighborhood weight.And then the breakpoint detection is introduced,the breakpoint edges are traced and connected by building tracing region.Finally the edge pixels are scanned and filled synchronously in four directions with the global threshold of the four-directional scanning length,and the accurate segmentation of the target is achieved.Experiment results show that compared with other algorithms,the proposed algorithm is of great advantage in segmentation accuracy,and is of high operating efficiency by using strong parallel strategy,and reaches the real-time requirement of the target segmentation.
