这是关于数字水印的攻击例程！经过调试，可以放心使用！(This is on digital watermarking attacks routines! After debugging, can be assured use!)

说明：  人工势场法避障 实现从势能高出往低处运动 ，实现路径规划 和避障(artificial potential)

可以画出双曲线的图形,比较好用,同时也可为大家编写画其他函数曲线提供借鉴.(Hyperbola can be drawn in the graphics, more convenient, but also for the preparation of U.S. painting other function curve for reference.)
