Sobel边缘检测算子的改进研究
摘要
Abstract
Aiming at deficiency of traditional sobel operator in edge detection, an improved algorithm is proposed. We add 45°、135°、180°、225°、270°、315°six direction pattern based on traditonal operator,and improving the method of weight selection, adjusting the parameter of every template. Using the improved algorithm to extract the edge of the experimental image. Simulation experiments show that, the improved algorithm has improved the precision of edge detection and the anti noise performance.关键词
