压缩包中的文件是对图像的像素值进行归一化，其中一个是对图像像素值归一化到０－１，另一个是对图像像素值归一化到０－２５５，可以根据自己的需要自行选择。其中，归一化到０－２５５的文件还可以作为图像统计直方图的预处理步骤。

sar图像去噪的几种新的方法，能量谱分析计算,基于kaiser窗的双谱线插值FFT谐波分析，均值便宜跟踪的示例，经典的灰度共生矩阵纹理计算方法，验证可用。

三相短路计算程序，计算任意地点三相短路后各支路电流和各节点电压(Three phase short circuit calculation program-After the three-phase short circuit in arbitrary locations, the current of each branch and the voltage of each node can be abtained.)

详细介绍matlab的FFT变换的实际物理意义，并通过具体事例具体分析，简单明了，方便易懂！绝对对你明白FFT变换的意义有很大好处和实用价值。(Details of the FFT transform matlab actual physical meaning, and through a concrete analysis of concrete examples, simple and clear, easy to understand! Absolutely right you understand the meaning of FFT transform of great benefit and practical value.)

水平集图像处理程序,利用一个新的变分公式进行图像处理，效果很好(Level set image processing program,we present a new variational formulation for geometric active contours that forces the level set function to be close to a signed distance function, and therefore completely eliminates the need of the costly re-initialization procedure.)

可以产生混合高斯信号信号的函数。自己可以调节混合信号的峭度。(Can produce mixed-Gaussian signal function. You can adjust the mixed signal kurtosis.)
