Hough变换用来在图象中查找直线。它的原理是：假设有一条与原点距离为s，方向角为θ的一条直线，直线上的每一点都满足方程 s=x*Cosθ+y*Sinθ，利用这个事实，我们可以找出某条直线来。这段程序，用来找出图象中最长的直线。-Hough Transformation is used for searching lines in an image . Here is the principle: Assume there is a line whoes direction is "sita" , and the distance from the origin to this line is s. So each point in this line satisfies the equation : s=x*Cos(sita)+ y*Sin(sita) . We can find out the lines based on this fact. And this programme is to find out the longest line in the image.

中值滤波是图像增强常用的方法。程序中参数Hori是一个布尔变量，若为真，做水平中值滤波，否则，做竖直中值滤波。-Median Filtering is the common method of Image-enhancing.In the application ,the parameter "Hori" is a BOOL variable,which is TRUE for the operation of Horizon Median Filter or FALSE for the Vertical Median Filter.
