DCT

对图像进行滤波，顶帽变换并计算中心，有图片，可直接运行。(The image filtering, top-hat transform and Computing Center, there are images which can be directly run.)

压缩感知和超分辨率论文，关于如何将低分辨率的图像如何重建成高分辨率图像，很有用(compressed sensing and super resolution)

本篇论文主要介绍地基云的自动检测！采用阈值分割！(This paper describes the automatic detection of the foundation of cloud! Using thresholding!)

基于扫描地形图的几何纠正算法研究。主要讲解了关于倾斜的数字图像的处理问题。(Scanned topographic maps based on the geometric correction algorithm. Mainly on the inclination to explain the deal with the issue of digital images.)

说明：  matlab编写的对极几何约束算法，用来剔除角点跟踪过程中的离散点(matlab prepared for a very geometric constraint algorithm, used to remove corner to track discrete points in the process of)

Random Walker图像分割Matlab源代码，需要安装图形分析工具箱，地址http://eslab.bu.edu/software/graphanalysis/，给出了一个应用例子。(Random Walker Image Segmentation Matlab source code, need to install the graphical analysis toolbox, address http://eslab.bu.edu/software/graphanalysis/, gives an application example.)

时移相位差校正法，通过时移，进行前后两次FFT分析，利用离散频谱对应峰值谱线的相位差以求出频率和相位校正量。(Phase difference correcting method by time-shifting. Make two FFT analysis before and after the time-shifting,and make use of the phase difference of the peak spectral lines to get frequency and phase correction amount.)

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.)

说明：  二值化处理图像，自动拟合椭圆并得到长短轴的大小。(Automatically fit the ellipse and get the size of the long and short axes)
