基于局部三进制模式的边缘检测方法

摘要

边缘检测是指检测图像中灰度突变的区域边界，其结果直接影响图像后续处理，有效和准确地提取图像的边缘是边缘检测的关键。利用局部三值模式对图像结构特征的表征优势，提出一种新的图像边缘检测算法，能够准确检测出边缘，和其它边缘检测方法比较，具有边缘检出率高和抗噪性能好的优势。%Edge detection is to detect the boundary of the region with great change in gray image ,its results will directly affect the follow -up image processing operations .The main purpose of edge detection is extract the edge of the image ef‐fectively and accurately .By using local ternary patterns with the superiority of expressing image accurately ,this paper pro‐poses a new image edge detection algorithm which can detect edge accurately ,compared with other edge detection meth‐ods ,it have high detection rate and good anti noise performance advantage .
