直线检测的代码，非常好用，对棋盘格图像的直线检测清晰准确。-Line detection code is very easy to use, straight-line detection of checkerboard images clearly and accurately.

数字图像处理，边缘检测，霍夫变换求取直线，简单实用的实例，选择一个待处理图像，可直接运行，可修改后满足自己的需求-Digital image processing, edge detection, Hof transform to obtain a straight line, simple and practical examples, an image to be processed, can be directly run, can be modified to meet their n

很大很全的图像处理算法，包括二值化、图像细化、直线检测、直线交点识别等(Large and very full image processing algorithms, including two values, image thinning, straight line detection, line intersection recognition, etc.)
