minimum spanning tree (MST) of a connected, undirected and weighted network is a tree of that network consisting of all its nodes and the sum of weights of all its edges is minimum among all such poss...
We present a method for hierarchical image segmentation and feature extraction. Thismethod builds upon the combination of the detection of image spectral discontinuities using Canny edge detection and...
Based on the graphic theory and improved genetic algorithm,an improved genetic algorithm to search the minimum spanning trees is given . The algorithm uses binary code to represent the problem of mini...
