提出了一种广义迭代收缩算法（GISA）非凸稀疏编码，可以解决稀疏编码的一些优化问题.希望能对大家有所帮助！(A generalized iterative contraction algorithm (GISA) is proposed to solve some of the optimization problems of sparse coding. We hope to be helpful to everyone!)

复杂背景下文字分割程序的源代码，可以很好的对文字进行分割(Text Segmentation in Complex Background program' s source code, can be a good segmentation of text)

说明：  可以实现基于matlab的加权平均方法的图像融合，亲测有效。(The weighted average method based on matlab can be used for image fusion)

数字图像处理英文版第三版60多M~很难找到！！希望大家珍惜再珍惜！(digital image processing English and third version,about over 60 M, difficult to find ,hope everybody cherish it !)

用小波变换进行图像增强，先对原始图像进行非下采样的小波分解，在对每一层的高频分解系数进行处理，得到变换后的小波系数，再进行小波重构。(Image enhancement using wavelet transform, the original image and non-sampling wavelet decomposition in the high frequency decomposition coefficients of each layer, get the wavelet coefficients after the transformation, then the wavelet reconstruction. )

说明：  基于自适应α-β滤波器的接收机跟踪环多普勒自补偿算法(Based on adaptive alpha beta filter satellite receiver loop of the doppler compensation algorithm design)

Camshift算法，即"Continuously Adaptive Mean-Shift"算法，是一种自适应的运动跟踪算法。它主要通过视频图像中运动物体的颜色信息来达到跟踪目的。(Camshift algorithm, namely " Continuously Adaptive Mean-Shift" algorithm is an adaptive motion tracking algorithm. It is primarily the color information of the object' s movement through the video images to achieve tracking purposes.)

说明：  通过双通道PCNN来实现多源图像融合，算法简单易于实现(image fusion using dual channel PCNN)

说明：  SSR、MSRCR、Retinex和暗通道四种去雾算法的matlab实现，亲测好用，改图片名可以直接运行，效果很好(The matlab implementation of SSR, msrcr, Retinex and dark channel defogging algorithms is easy to test and use. Changing the image name can run directly, and the effect is very good)

W.T.Freeman 经典 基于例子的超分辨率重构matlab源码，图片自己可加，经测试可用(WTFreeman classic example of super-resolution reconstruction based on matlab source code, images themselves can be added, the test can be used)
