二维图像运算示例 圆形图、交叉点运算、求点-Examples of two-dimensional pie chart image computing

给定栅格图像及其变形后的栅格图像，请你首先确定各栅格交叉点的位移，然后采用控制栅格的方法编写实现图像几何校正的程序-Given its raster image raster image after deformation, you first determine the displacement of each grid intersection, and then using the method of preparation of the control grid of image geo

特征提取：重点是几何特征环,交叉点,端点和变换 不错的-Feature extraction: with a focus on the geometric feature of ring, intersection, endpoints, and transform is good
