image registration by sift and surf

介绍ransac的matlab程序，用在图形图像基于特征点的配准中 可以有效的剔除错误的匹配点 (介绍ransac的matlab程序，用在图形图像基于特征点的配准中 可以有效的剔除错误的匹配点 )

利用小波变换的去噪程序！和中值滤波进行对比！(The use of wavelet transform denoising procedure! And median filtering comparison!)

说明：  此算法可以实现任意两个图像的配准（整体平移） (This algorithm can achieve any two image registration (the overall translation))

一款新的数据分析工具，非常简单易用，用在系统辩识中(A new data analysis tools, very easy to use, used in System Identification)

本设计是基于超像素的图像分割代码，可以实现图像前景和后景的分割。没有人机交互界面GUI。( U672C u8BB u8B1 u662F u57FA u5FF u524F u5BF u5BF u5DF u7D0 u7R0 u7684 u56FE u50CF u5206 u5272 u4EE3 u7801 uFF0C u53EF u4E5 u5B9E u73B0 u56FE u50CF u524D u666F U548C u540E u666F u7684 u5206 u5272 u3002 u6CA1 u6709 u4EBA u673A u4EA4 u4E92 u754C u9762GUI u3002)

matlab与C++混编的grabcut分割程序，只需画框即可提取目标(grabcut algorithm)

数字图像处理的非常面全的图片，包含有各种格式的和大小的。(there are many kids of images that used to digitial image pricessing,including lena,boat,cman images)

说明：  关于数字图像一些典型隐写的隐写分析。隐写、分析和提取的讲解(Steganalysis of Some Typical Steganography in Digital Images)

图像识别，包括人脸识别和虹膜识别，在数字图像中虹膜位置的有效定位是虹膜识别的关键问题。用一种基于主动轮廓线模型的方法定位虹膜的位置，先用灰度投影法检测出瞳孔内的一点作为瞳孔的伪圆心，该圆心只要能落在瞳孔内部即可。(Image recognition, including face recognition and iris recognition, iris position in the digital image of the iris recognition and effective positioning is the key issue. Using a model based on active contour method of positioning the iris position, the first gray projection method used to detect a point within the pupil as a pupil of the pseudo-center of a circle, the center of a circle can be as long as it falls within the pupil.)

fbp算法实现CT重建，包括不同投影个数、探测器个数和噪声对重建后图像的质量的影响。(FBP CT reconstruction algorithm, including the number of different projection, and the number of detector noise on the reconstructed image quality.)
