说明：  基于活动轮廓模型的图割算法，实现图像的高效分割！非常好的代码。希望帮助大家！(Graph cuts based active contours which is used for image segmentation.Excellent source code!)

该源代码可以直接下载下来使用，而且是地地道道的对RGB图像进行分割，我已经测试通过了。(The source code can be directly downloaded to use, but also out-and-out on the RGB image partition, I have the test passed.)

用surf和ransac实现两幅图像配准(Registration of two images with surf and RANSAC)

说明：  傅里叶谱与频域低通滤波 (a)从图书网站下载图4.41(a)并计算其(居中)傅里叶谱。(b)显示频谱。(c)在等式(4.8-7)中实现高斯低通滤波器。您必须能够指定结果2D函数的大小，M x N。此外，您必须能够指定高斯函数的中心位置。(d)从图书网站下载图4.41(a)，并对其进行低通滤波，以复制图4.48中的结果。(Fourier Spectrum and Lowpass Filtering in Frequency Domain (a) Download Fig. 4.41(a) from the book web site and compute its (centered) Fourier spectrum. (b) Display the spectrum. (c) Implement the Gaussian lowpass filter in Eq. (4.8-7). You must be able to specify the size, M x N, of the resulting 2D function. In addition, you must be able to specify the location of the center of the Gaussian function. (d) Download Fig. 4.41(a) from the book web site and lowpass filter it to duplicate the results in Fig. 4.48.)

两种不同量化步长的图像采样编码重够后的图像比较(Comparison of the two different images of the image sample quantization step size after encoding the heavy enough)

NSCT轮廓波变换程序，用于图像融合，有图有解释说明(NSCT image fusion)

采用五种算子对图像进行空域滤波处理，实现去模糊效果。(Using five kinds of operators on the image spatial filter processing, and to the blurring effect.)

说明：  根据差影法采取视频中两帧进行对比，得出差别的地方进行目标特征提取(Comparison of two frames in video based on difference method,And get the difference to extract the target features)

说明：  读图然后根据图像的对象，进行边缘检测，椭圆拟合(Read the image and then carry out edge detection and ellipse fitting according to the object of the image)

图像相似性检测的PPT，比较全面的总结，对主要用到的特征提取和特征匹配算法都有基本的介绍。(Image similarity detection of PPT, a more comprehensive summary of the main use of the feature extraction and feature matching algorithm has the basic The introduction.)
