| Abstract: | This paper presents a method of image segmentation based on entropy for automatically calculating threshold,after analyzing features of the samples of transmission line images.The method could automatically calculat threshold for image segmentation based on image's information entropy,and it does a good job at segmenting the foreground consisting of the main parts of the transmission line from the background.The result of experiment indicates that the algorithm can satisfy the need when doing the real-time ... |
