自己编写图像平滑算法：均值滤波和中值滤波，设置不同的均值滤波模板，以得到最好的图像输出结果。(I have written the image smoothing algorithm: mean filter and median filter, mean filter set different templates to get the best image output.)

说明：  通过hough变换求图像中的圆的参数（圆心坐标和半径）(Through the hough transform for image circle parameters (center coordinates and radius))

超像素分割程序，既有原码，也有可执行程序，验证过，好用。(Super-pixel segmentation procedure, both the original code, there are executable programs, proven, easy to use.)

用哈夫曼算法对图像进行压缩， 1.颜色模式转换及采样； 2．DCT变换（离散余弦变换）； 3．量化；4．编码（有算术编码和哈夫曼编码两种，这里采用哈夫曼编码）

傅里叶梅林变换实现图像配准，对旋转，缩放，剪切，平移都有效(Fourier Mellin Transform for image registration, valid for rotation, scaling, cropping, shifting)

一种基于彩色图像分割的余弦相似度的快速的谱聚类算法(A Fast Spectral Clustering Algorithm Based on Cosine Similarity for Color Image Segmentation)

通过利用自动阈值法，获得图像中颗粒粒径的分布，并将粒径分布进行排序。(By using automatic threshold method to obtain the particle size distribution of the image, and the particle size distribution of the sort.)

opencv SIFT源码详细分析，代码能够准确实现(opencv SIFT detailed analysis of the source code can achieve accurate)

surf特征提取算法，较sift优良，包括示例和实验图片，还有算法原文(surf feature extraction algorithms, the more sift fine, including examples and experimental images, as well as the original algorithm)

行人检测HOG+SVM进行图片中行人检测，提供训练用的pos和neg样本，效果还可以；没有SVM工具箱的，压缩包里已经提供了，安装一下即可(Pedestrian detection HOG + SVM for pedestrian detection in pictures, providing POS and neg samples for training, the effect is good; without SVM toolbox, the compression package has been provided, just install it.)
