高斯粗糙表面的散射系数，输入参数含波长，需要regeng.m产生高斯粗糙表面。(rs1dg computes the bistatic scattering coefficient for Gaussian rough surfaces with Gaussian spectrum.)

此程序为shearlet程序，用于对图像进行分解变换，有兴趣的可以下载(This procedure for shearlet program for image decomposition transform, are interested can download)

国外的一个车牌识别程序，主要是基于颜色特征提取分割的，内置神经网络。(A license plate recognition program abroad, mainly segmentation based on color feature extraction, built-in neural networks.)

softcast的2d dct实现，先对图像转灰度图，得到的亮度信号矩阵做DCT 变换(softcast of 2d dct implementation, the first image to grayscale, luminance signal obtained by DCT transformation matrix do)

将一副图像进行rgb分离，并将R G B 的各个分量显示出来。(the sepration of rgb and show the sepration )

说明：  “求RGB转HSI空间小程序.m”为主函数调用rgb2hsi.m，由于matlab没有自带这个函数，所以自编了一个，用于进行阴影去除。( Seeking RGB to HSI space program. M the main function call rgb2hsi.m, as a result of matlab does not own this function, so a self-compiled, used for shadow removal.)

灰度变换元代码，用于matlab7.0以上版本(Picture Process)

说明：  本程序主要对遥感图像实现三种处理：几何校正、图像增强和图像配准。这三种处理都可以独立实现，然而对于原始的遥感图像将这三种处理依次进行效果更佳。(This program mainly deals with three kinds of remote sensing image processing: geometric correction, image enhancement and image registration. These three kinds of processing can be realized independently, but for the original remote sensing image, the effect of these three kinds of processing in turn is better.)

对于图像进行ANORLD变换，在图像嵌入水印的过程中，可以对要嵌入的水印图像先进性置乱操作，可以有效地抵抗剪切攻击(For images ANORLD transform, watermark embedding in the image of the process, can the watermark image to embed the advanced nature of the scrambling operation, can effectively attack the shear resistance)
