光谱微分（一阶、二阶微分）对高光谱遥感图像进行最佳波段选择 (Spectral radiant brightness)

压缩感知CS——采用小波变换进行稀疏表示，高斯随机矩阵为观测矩阵，重构算法为SP算法，对256*256的lena图处理，比较原图和SP算法在不同采样比例(0.74、0.5、0.3)下的重构效果，并各运行50次，比较算法性能PSNR和每次的运行时间(Compressed sensing CS- using wavelet transform as sparse representation, Gaussian random matrix as the observation matrix and SP algorithm as the reconstruction algorithm. Compare lena figure and the reconstruction results using SP algorithm at different sampling ratio (0.74,0.50.3),then each runs 50 times, compare the performance of PSNR and each running time)

用halcon编写的代码实例，用来给初学者学习(Use halcon code examples, for beginners learning )

自适应直方图均衡算法，对彩色图像的处理，有很好的效果。尤其是针对医学图像，内窥镜图像。(Adaptive histogram equalization algorithm for color image processing, have a good effect. Especially for medical images, endoscopic images.)

在matlab环境下基于pocs（凸集投影）的图像重建(Based in the matlab environment pocs (convex projection) of image reconstruction)

这是一种彩色图像去雾算法，可以识别物体的轮廓，但是同时也会加强这些轮廓，虽然去雾效果不错，但是会加强轮廓！(This is a color image to fog algorithm can identify the contours of the object, but will also enhance the outlines, although to fog effect is good, but will strengthen the profile!)

计算图像调制传递函数（MTF）。提高图像清晰度。可以处理普通图像以及卫星照片(Calculation of image modulation transfer function (MTF). Improve image clarity. Can deal with ordinary images and satellite photos)
