中文说明： 实现了图像的灰度化并进一步用于视频监视控，包括调制，解调，信噪比计算，插值与拟合的matlab实现，是国外的成品模型，可实现对二维数据的聚类，算法优化非常好，几乎没有循环。
English Description：
To realize the gray-scale image and further control for video surveillance, including modulation, demodulation, signal to noise ratio calculation, interpolation and fitting matlab implementation is foreign product model, can achieve the two-dimensional data clustering, algorithm optimization is very good, almost no circulation.
