KLT point match:Detection and Tracking of Point Features.

本压缩文件利用Matlab制作了一个能识别居民身份证号码的系统，使用图像处理技术，实现了计算机识别数字的功能。(The compressed file using the Matlab made a system can identify the identity card number, using image processing technology, realized the function of the digital computer identification. )

本程序包是基于多分辨率分析的图像融合算法，其中包括基于区域的融合算法。对应程序有相关的文章，是学习图像融合最有用的资料。(This package is based on the analysis of multi-resolution image fusion algorithms, including region-based fusion algorithm. Procedures related to the corresponding articles, image fusion is to study the most useful information.)

样条函数用于图像放大；可放大任意倍数；五次样条函数的构造 (five splines function)

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.)

对matlab中的GUI界面设计进行讲解并附有案例，例如如何进行界面菜单和控件设计，不同GUI之前函数传递，并讲解了如何调用自身函数(Matlab GUI interface design to explain the attached case, for example, how to interface menus and controls design, the different GUI function is passed before, and explain the how to call its own function)

Sobel算子边缘增强算法，利用梯度下降原理边缘化图象(Sobel operator enhancement algorithms, using gradient descent principle marginalized image)

说明：  图形界面计算psnr和ssim，直接输入原始图像和处理后的图像的psnr和ssim值，分别在Y通道和RGB通道(The graphical interface calculates PSNR and ssim, and directly inputs the PSNR and SSIM values of the original image and the processed image in Y channel and RGB channel, respectively)

极坐标和平面坐标的转换，在图像处理中可以很好解决在一个坐标下不能解决的问题。(Polar coordinates and plane coordinates conversion, in image processing can be solved in a coordinate system can not solve the problem.)

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.)
