You are given an n x n grid , a starting position on the grid and a goal location. Each point on the grid is assigned an integer, giving its elevation. It is possible to move from a location to any of its 4 neighbours (except at a boundary). The cost of such a move in 1 the absolute value of the difference in elevation. However, if the difference between two points is greater or equal to 4, this represents an impassible cliff

这是利用python+opencv编写的，行人检测代码，另配有检测样图，测试可用(this is a code for person detect,it function is normal)

该代码是基于Python写的，可基于LSB机制的实现信息隐藏，并可以对隐藏的信息进行提取
