| 摘 要： | 从利用边缘像素空间关系和抑制伪边缘的角度出发，提出了一种基于图像自身信息的图像边缘检测阈值自动设定方法，并阐述了其物理意义。本文方法利用图像边缘连续度衡量边缘像素的空间关系，其极大值蕴含着边缘像素增长模式的转换；利用边缘段增量识别伪边缘的出现。对比实验结果表明，本文方法具有良好的稳定性和可靠性。

| Abstract: | Considering the spatial relationship among edge pixels and the false edges suppression,an unsupervised threshold selection method for edge detection is proposed based on the image self-information,and its physical meaning is interpreted in detail.The spatial relationship edge pixels is evaluated by the connection indexes of edge maps whose maxima imply the transformation of edge pixels’ increasing mode;and the false edges are recognized according to the increment of edge segments.The results of comparative experiments indicate that the proposed method has excellent stability and reliability. |
