八个方向的sobel边缘检测算法

nca,近邻成分分析，距离度量学习里常用的。(nca)

图像色彩空间转换，hsi空间，cmy，yiq，yuv等等(Digital Image Color Space Conversion)

简单的Halcon 找圆算法，首先进行圆检测(识别圆、圆拟合)，再找出坐标位置(A simple Halcon algorithm for finding circles firstly conducts circle detection (identifying circle and circle fitting), and then finds the coordinate position)

基于灰度共生矩阵的图像检索技术。完整的特征提取、特征描述、特征匹配以及结果返回。(GLCM-based image retrieval techniques. A complete feature extraction, feature description, feature matching and the result returned.)

用画笔绘制圆角矩形，椭圆，饼形，并用不同颜色画刷进行填充。(Draw a rounded rectangle, ellipse, pie with a brush, and brush with a different color fill.)

数字图像处理(matlab版) 自带的 DIPUM_toolbox, v1.1.4，m文件(dipum toolbox v1.1.4 m files)

利用模糊C聚类（FCM）的方法对彩色图像进行分割，期中可以用不通的特征向量来表征图像的特征(The method of fuzzy C clustering (FCM) is used to segment the color image. In the period of time, the feature vectors can be used to characterize the features of the image.)

openCV中文版 附目录 本书主要介绍: 1.透彻介绍OpenCV 2.从摄像机获取输入 3.图像的变换 4.图像的分割和形状的匹配 5.模式识别，包括人脸检测 6.二维和三维场景中的跟踪监测 7.根据立体视觉进行三维重构 8.机器学习算法(the openCV Chinese edition with catalog book describes: a thorough introduction to OpenCV get input from the camera image transform image segmentation and shape matching 5 pattern recognition, including face detection of two-dimensional and three-dimensional tracking and monitoring of the scene based on stereo vision for three-dimensional reconstruction of 8. machine learning algorithm)

说明：  超像素实现图像分割，可以实现彩色图像分割(An EM algorithm is used for image segmentation.)

利用DNA加密，将图像加密，啊啊啊啊啊啊啊啊啊啊(Encrypting the image by DNA and encrypting the image)
