运用pca算法降维，提取主要特征值，从而达到降维目的(Dimensionality reduction using pca algorithm, extract the main features of the value of)

matlab中值平滑处理,主要是用5点平滑和3点平滑实现(matlab median smoothing was used in 5-point smoothing and 3 points to achieve smooth)

PCB板检测的大概流程如下：首先存储一个标准PCB板图像作为参考标准，然后将待检测的PCB板图像进行处理，比较与标准PCB图像的差异。根据差异的情况来判断缺陷类型。(The approximate process of PCB board detection is as follows: first, a standard PCB board image is stored as a reference standard, and then the PCB board image to be detected is processed to compare the difference between the standard PCB image and the standard image. The type of defect is judged according to the difference.)

利用EM算法进行的彩色图像分割，利用EM算法进行的彩色图像分割(The use of EM algorithm for color image segmentation)

说明：  一种彩色图像的边缘检测算法，检测效果非常好，它是对Canny算法的改进，定位好，相应标准高，检测率高，误检率低(a kind of edge detection algorithm.The algoritlun employs amultpassprocessing approach that re}novesnoisefrom theRGB componentswith apre-filter, with the color edge detector then based on an extended gray scale edge gradient tern plate detector.)

数字视频图像处理算法的经典书籍：数字视频和高清电视的算法和接口。(Digital video image processing algorithm of the classic books: Digital Video and HDTV Algorithms and Interfaces.)

雷达探测开关，用于检测前方是否有移动的物体?(Radar detection switch for detecting whether there is in front of the moving object?)

提取并显示鼠标所在图像点的颜色，C++精选学习源码，很好的参考资料。(To extract and display the image color, select learning C++ source code, a good reference.)

说明：  该节主要介绍下matlab下的光流法以及一个研究物体检测方面的一个较好的工具箱 ：Piotr’s Computer Vision Matlab Toolbox .将这两个工具箱及其里面所有文件的路径都添加到matlab路径中去，这样的话基本上是可以用了。 Piotr’s 的工具箱里面的函数很多，也涉及到了很多方面，更主要的是关于目标检测方面的。(This section mainly introduces the optical flow under Matlab and a better toolkit for researching object detection: Piotr 's Computer Vision Matlab Toolbox. Add the two toolkits and all the files in the path to the MATLAB path, which is basically useful. There are many functions in the toolbox of Piotr 's, and there are many aspects involved)
