仿qq截图功能，如下图

图像条纹提取，包括滤波降噪，确定条纹rio区域，重心法求条纹中心(Image stripes extraction, including noise filtering, determine stripes rio area, the center of gravity method for stripes)

利用摄像头工具箱标定得到的内部参数还原透视图像为“鸟瞰图”。本例中使用的图像时棋盘格。(Using the internal parameters obtained from the camera calibration toolbox. reducting perspective images as the "bird s eye view". In this case, use the image of the checkerboard.)

基于自适应的区域选择和自适应的正则化得图像去模糊和超分辨处理，试过可以用(Based adaptive region selection and adaptive regularization was image deblurring and super-resolution processing)

any help to perform DCT IDCT walsh inverse walsh on image

c++实现的sift，可以分步观看实现效果(c++ implementation of the sift, you can watch step by step to achieve results)

sift算法具有旋转不变性 提取的特征点效果非常的好 用于图像配准中

说明：  运用OMP、BP、StOMP及MP算法对lena图像进行重构。(Use OMP, BP, StOMP and MP algorithms to reconstruct the lena image.)

本代码是使用matlab编写的harr特征的代码，值得大家研究和参考(This code is the use of matlab prepared harr characteristics of the code, it is worth study and reference)

Jianchao Yang 的基于稀疏表示的单幅图像重建的原始代码，先将高低训练图像分块，再将块训练成高低字典，将测试图像映射到低字典上，得到系数，再乘以高子典就得到最后的图像。对学习超分辨率同学的参考作用很大。(This is the original matlab code for super resolution by Jianchao Yang 。The method is sparse represent based on the overcomplete dictionary。)
