focuss算法 关于图像稀疏性分解中字典学习的经典算法 和大家一同分享 (focuss algorithm on the sparse image decomposition in the dictionary of the classical learning algorithm and we share)

说明：  相机是将三维世界坐标系中的坐标点映射到二维图像平面的过程能够用一个几何过程描述，最简单模型称为针孔模型。 因为相机镜头透镜的存在，使得光线投影到成像平面过程中产生了畸变。(Camera is the process of mapping coordinate points in three-dimensional world coordinate system to two-dimensional image plane, which can be described by a geometric process. The simplest model is called pinhole model. Because of the existence of camera lens, the light rays are distorted when they are projected onto the image plane.)

利用Haar-like算法提取人脸特征，在matlab软件中进行人脸检测。(Haar-like algorithm is used to extract face features and face detection in MATLAB software.)

说明：  LK光流法算法，基于LK光流法的Matlab算法，本人自编(LK Optical Flow In Matlab)

人民邮电出版社，《VC++数字图像处理典型算法及实现》-- 第9章图像分割。 包括图像的并行边界分割、串行边界分割、并行区域分割、串行区域分割、Canny算子的实现等源代码(Posts )

图象分割中应用较多的ostu大津阈值法,matlab源代码(Application of image segmentation ostu more Otsu threshold method, matlab source code)

该程序主要是对一幅图像进行动漫风格化 总体上，把照片变成动漫化风格分以下几步： （1）膨胀图片让其亮暗分明 （2）区域平滑 （3）增强锐化，以突出显示边缘线条。(The program is mainly a cartoon style animation style On the whole, take the photo into the animation style and divide the following steps. (1) the expansive picture makes it bright and dark (2) regional smoothness (3) sharpening to highlight the edge lines.)

图像处理中的一些常用代码，包括：腐蚀操作 开启和闭合操作 形态学边界提取 形态学骨架提取 直接提取四个顶点坐标(Some of the commonly used image processing code, including: Opening and closing operation of corrosion morphology boundary extraction morphological skeleton extraction to extract four vertex coordinates)

说明：  这是我们数字图像处理课程的大作业，我自己用matlabGUI做了一个界面，希望对大家有用，谢谢！(This is a large digital image processing program operations, for my own use matlabGUI made an interface and hope for all of us, thank you!)

为解决PCA不适合多指标综合分析中非线性主成分分析的问题 ,采用核主成分分析 (kpca)方法 ,对我国不同地区 16种腐乳的品质进行了综合评价。 (PCA is not suitable to address the many indicators of a comprehensive analysis of non-linear principal component analysis of the problem, using Kernel Principal Component Analysis (kpca) method, 16 kinds of different regions of our country the quality of fermented bean curd had a comprehensive evaluation.)
