这是一个图像处理时用到的程序 可作为图像处理用非常有价值(This is an image processing procedures can be used as image processing with very valuable)

基于matlab的JPEG编解码程序。里面有2个程序，一个是程序是编解码过程，一个纯编码过程。含解释。(Program based on Matlab JPEG codec. There are two programs, one program is the process of encoding and decoding, a pure coding process. Containing explained.)

给予稀疏编码的原理将10幅自然图像进行系数分解成为图像基。(Given to the principle of sparse coding will be 10 coefficients of natural images into separate image-based.)

火灾探测中火焰图像分割方法研究,比较实用。(Fire detection fire image segmentation, more practical.)

在计算鬼成像当中，用于生成计算散斑，有了计算散斑 可以做仿真或者其他用途(In the calculation of ghost imaging were used to calculate the generating speckle, speckle can do with computing simulation or other purposes)

利用PCA检测图像的复制粘贴区域。检测效果良好。(PCA was used to test digital image s copy and paste area.)

已知对应点，可以求出仿射变换。只需要三个点就可以。(Known corresponding points, affine transformation can be obtained. Only need three points as you can.)

说明：  matlab图像去模糊算法代码，使用两倍长度的点扩散函数进行维纳滤波，模糊图像加入随机噪声，计算噪声信号功率比，使用噪声能量和图像一维自相关函数进行维纳滤波，模糊后的图像，减小噪声能量进行规则化滤波，增大拉格朗日乘子进行滤波，继续对恢复的图像反卷积，产生模糊图像，最初的PSF，显示最初PSF下恢复的PSF。(MATLAB image deblurring algorithm code, using double-length point spread function for Wiener filtering, adding random noise to blurred image, calculating noise signal power ratio, using noise energy and image one-dimensional autocorrelation function for Wiener filtering, blurred image, reducing noise energy for regular filtering, increasing Lagrange multiplier for filtering, continue to restore the image. Like deconvolution, a blurred image is generated. The original PSF displays the restored PSF under the original PSF.)

jpeg编码工程(YUV2RGB) 文件中含有说明文件,保证可以使用(jpeg encoding works (YUV2RGB) file contains the documentation to ensure that you can use)
