量化离散余弦变换系数的程序实现及其效果的检测。过程中使用了8x8的分块方法。首先计算每块的离散余弦变换（DCT)；然后量化了DCT的系数； 最后进行了反离散余弦变换(iDCT). 程序中还可以设定缩放系数。(Quantify the discrete cosine transform coefficients procedure and its effect detection. The process used in the 8x8 sub-block method. First calculate the block discrete cosine transform (DCT), quantization of the DCT coefficient Finally, the inverse discrete cosine transform (iDCT) program can also set the scaling factor.)

图像分类程序，此图像分类采用 SIFT + Kmeans 聚类的方法，然后调用 MLP 对其特征进行分类处理，速度实现比较快，正确率高(Image classification procedures, the use of this image classification method SIFT+ Kmeans clustering, and then call the MLP classification of its features, faster speed to achieve the correct rate)

几种全参考图像质量评价标准，例如VIF、IFC、VSNR、PSNR、MSE等。(Several full reference image quality assessment standard, such as 2 VIF is based, the IFC, VSNR, PSNR, MSE and so on. )

改进的harris角点检测代码，应用于基于特征的遥感影像配准中，在经典harris算子基础的改进，提高角点检测的准确度(improvement of harris corner detection program，applied in RS imagery registration based on features，the operator improved on the base of the classical one，the accruacy has been enhanced )

基于SIFT特征的遥感影像自动配准.rar (SIFT-based remote sensing image characteristics of automatic registration. Rar)

说明：  基于contourlet的图像融合利用的融合策略是取像素绝对值最大。此方法用得较少，有学习价值(Contourlet based image fusion using the fusion strategy is to take the absolute value of the maximum pixel. This method is used less, the value of learning)

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.)

对图形的旋转 有不错的效果 可以试试 让图形从左到右(Rotation pattern has a good effect can try)

图像的读入，放大，cany检测，二值化，灰度化，任意角度旋转(Read image, zooming, cany detection, binarization, gray, and arbitrary rotation angle)

ELMAN计算方法，改进的算法,非常好用(ELMAN calculation algorithm, the improved，use very well)
