通过滤除图像中混杂的正弦噪声实现功能，屡噪并进行频率分析使得图像像素点清晰纯净-Through the filter image noise mixed to achieve sinusoidal function, and the frequency of repeated noise analysis makes clear pure pixel Image

对形图像的经过边缘提取后得到的二值图像边缘进行细化，提取单像素的边缘，使得边缘是成为清楚的单像素的边缘。-After images of the shape after the edge extraction of the binary image to refine the edge, the edge extraction of a single pixel, making the edge is to be clear of the edge of a single pixel.
