摘要
针对因漏检而断裂的图像边缘图中的边缘连接问题,提出基于主动生长的边缘连接算法。先检测边缘图中端点的位置和方向,再在端点处进行主动边缘生长并通过退化操作实现边缘的正确连接;通过退化和约束生长实现对边缘图的去噪处理。实验表明,本算法在不增加边缘图噪声的情况下,很好地实现了对断裂边缘的有效连接,有利于后续的图像分割、表达和匹配等处理。
This paper discussed an edge linking algorithm based on autonomous edge growing for discontinuity edge of edge image caused by missed detection. After detected the position and direction of end points of edge line in edge image, edge would be grown along its original direction and the withdrawing operation would be used to make the correct edge linking. The noise of edge image would be decreased by withdrawing and restrained growing operation. Experiments show that the algorithm has excellent performance in edge linking of edge image in different cases, and the noises can not be increased in the same time, it is in favor of subsequent image processing such as image segmentation, expressing and matching.
