令x(n)=5exp(j*0.15*n*n)+6exp(j*300n-j*0.15*n*n) ，w(n)为高斯窗函数。试用matlab软件，取不同长度的窗函数，分别求x(n)离散短时傅里叶变换，并进行信号重构。(ORDER x (n) = 5exp (j* 0.15* n* n)+6exp (j* 300n-j* 0.15* n* n), w (n) for the Gaussian window function. Trial Matlab software, take different lengths of the window function x (n), respectively, seek to discrete short-time Fourier transform, and to reconstruct the signal.)

说明：  本rar文件是图像超分辨率重构的网络模型RCAN的代码，可以成功运行(This rar file is the code of the image super-resolution reconstruction network model RCAN, which can be run successfully)

说明：  Make_chaos 将图像进行置乱，生成乱序图，以便进行水印嵌入(Make_chaos will Scrambling images, generate disorder plans for embedding)

实例如图所示

基于亚像素运动估计算法的块匹配运动，有源码跟参考文献，初学的小伙伴可以看看(Block-matching motion estimation algorithm based sub-pixel motion, there is source code with references, beginner can look at a small partner)

hough变换提取椭圆,可以从二值图像中提取出椭圆(The ellipse can be extracted from Hough transform, and ellipse can be extracted from the two valued image.)

基于meansheift的彩色图像分割方法。其中keyprogram.m为主程序。meanshift为调用函数(Color image segmentation method based meansheift. Where keyprogram.m main program. meanshift call the function)

MSTAR数据库中的部分SAR图像，大小限制只传12张，分辨率较大约为1476*1784，适合SAR图像的压缩恢复处理(MSTAR part of SAR image size limit only pass 12, higher resolution of about 1476* 1784, for compressed SAR image restoration processing)

说明：  利用vc++实现avi文件图像截取，avi图像即视屏图像(Use vc++ Achieve avi file image capture, avi video image that is, images)

说明：  用于数字抠图的源代码，外国人写的，非常好用(image spectral matting code)
