在同一坐标内，分别用不同线型和颜色绘制曲线y1=0.2e-0.5xcos(4πx) 和y2=2e-0.5xcos(πx)，标记两曲线交叉点。- In the identical coordinates, separately uses different linear and color curve y1=0.2e-0.5xcos (4 pi x) and y2=2e-0.5xcos (pi x), marks two curves intersections.

图像中交叉点提取算法，用matlab编写，很容易理解-Cross-point of the image extraction algorithm using matlab write, it is easy to understand

给定栅格图象及其变形后的栅格图象，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象几何校正的程序-A given image and deformed grid raster images, you first determine the displacement of each grid intersection, and then using the control method of preparation of raster image geometric correc
