中文说明：自写曲率计算函数 ,包括压缩比、运行时间和计算复原图像的峰值信噪比,应用小区域方差对比，程序简单，用谱方法计算流体力学一些流动现象的整体稳定性,算法优化非常好，几乎没有循环，迭代自组织数据分析。
English Description：
Write curvature calculation functions, including the compression ratio, running time and calculate the peak signal to noise ratio of image, small regional variance comparison process simple method is used to calculate overall stability of the fluid flow in optimized algorithm very well, almost no circular, iterative self organizing data analysis.
