Community detection is a hot topic for researchers in the fields including graph theory, social networks and biological networks. Generally speaking, a community refers to a group of densely linked nodes in the network.

Canny Edge Detector has been widely used in biological related areas to detect edges of objects in an image. It has been recognized as an efficient edge detector, but the two thresholds that need to be provided by users remains an issue. In this paper, we develop an Auto-thresholding Edge Detector which applies k-means clustering algorithm for gradient intensity partitioning. The partitioned edge...
