用Canny算子检测图像的边缘 P0404：图像的阈值分割 P0405：用水线阈值法分割图像 P0406：对矩阵进行四叉树分解 P0407：将图像分为文字和非文字的两个类别 P0408：形态学梯度检测二值图像的边缘 P0409：形态学实例——从PCB图像中删除所有电流线，仅保留芯片对象-with Canny operator to detect the edges in the image P0404 : image thresholding segmentation P0405 : water

使用radon变换进行直线检测,matlab源文件-Line detection using the radon transform

实现在matlab环境下的直线检测，效果很好-Straight line detection, with good results achieved in the matlab environment

基于matlab的图形检测，主要针对直线的检测-Matlab-based graphical testing, mainly for line detection,,,,,,,,,,,,,
