自己设计的GVF模型图像分割程序，改进了初始轮廓的选择方法，快速分割。(GVF model designed image segmentation process to improve the initial outline of the selection method, rapid division.)

图像处理之Matlab特征提取和表达-一些规则图形的特征提取(Matlab feature extraction and expression in image processing - feature extraction of some regular patterns)

可以实现bmp图象的sobel边缘检测运算，并含有可图象重建功能。简单，易懂，使用了DIB接口，适合作数字图象处理的初学者作参考(Bmp images can be achieved sobel edge detection operator, and contains the reconstruction of functional images. Simple, understandable, the use of the DIB interface, suitable for beginners of digital image processing for information)

利用MATLAB实现了视频图像行人识别与检测，(Using MATLAB to achieve video image pedestrian recognition and detection,)

图像重构实现干涉条纹缺陷图的缺陷检测，能很好的滤除条纹，得到缺陷(Interference fringe image reconstruction to achieve defect detection defect map can be a very good filter stripes)

说明：  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.)

采用8个阵元，利用CAPON算法，进行DOA，画出波达方向估计误差随着信噪比变化的曲线图(Eight elements, the use of the CAPON algorithm of DOA draw the DOA estimation error changes with the SNR curve)

用matlab进行图像检索，基于边缘直方图（EHD）描述子，它是MPEG-7标准中提出的一种边缘描述子，它具有描述图像亮度变化的方向和频率的能力。资料为主程序代码。(Matlab for image retrieval, based on the description of the edge histogram (EHD) sub, it is proposed in the MPEG-7 standard descriptor an edge, it has the direction of the change and the frequency of the described image brightness capability. Data the main program code.)

对于遥感图像，研究了一种基于基于Contourlet变换和分形压缩方法，方法具有一定的实用价值，程序包中有实验图片。(For the remote sensing images, a kind of transformation based on Contourlet and fractal based compression methods, the method has some practical value, experimental pictures in the package.)

K-means彩色图像分割，有实验报告，main文件中还有区域生长的算法。(K-means color image segmentation, with experimental report.)
