Edge Detection Based on Robust Least Squares Support Vector Machines with Multiple Kernel
-
Abstract
Based on the powerful nonlinear mapping ability of kernel learning,a novel method for edge extraction was proposed to overcome the over-fitting of original LS-SVM and improve the robustness of original LS-SVM.Particle Swarm Optimization(PSO) algorithm was used to the optimize the parameters.Compared with Canny method,BP neural network and standard LS-SVM,it is shown that the proposed method is effective and has better performance than other algorithms under the same condition,it is a very practical image processing algorithm.
