小球撞壁变色的matlab程序，以一图片为背景，小球随机移动，小球撞壁时颜色改变-The ball hit the wall discoloration matlab program

移动图片，修改一下，可以在整个坐标系移动-move the picture

采用matlab编程语语言，可在二维图片（对称）移动鼠标，自动检测出边缘轮廓，将二维图片转化为3维立体图片。(Using MATLAB programming language, the mouse can be moved in two dimensional picture (symmetrical), the edge contour is detected automatically, and the two-dimensional picture is transformed into
