对特征选择与提取进行介绍，及几个特征提取方法简介(For feature selection and extraction are introduced, and several feature extraction methods Introduction)

自己编写的C++小程序，十字算法，用到KD树，能够有效进行点云去噪，压缩数据(I have written a small program C++, cross algorithm used in KD tree, the point cloud can be effectively de-noising, compression of data)

三视图，用二维图像显示三位图像，分主视图，俯视图，侧视图(view)

说明：  马氏过程的应用很广， 机器人路径计划， 自动飞行器导航，多目标跟踪， 电梯计划， 网络交换和路由， 银行客户保有等等。(Application of Markov process is broad, robot path plan, automatic vehicle navigation, multi-target tracking, lift plans, network switching and routing, bank customers to maintain and so on.)

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.)

简单起见，这里设定阈值为122，即最大灰度的一半(the sake of simplicity, this threshold value is set to 122, the largest gray half)

本程序用于计算图像相似性,计算图像的7个不变矩，包含图像、源程序、网上的说明(3D_Moment_Invariant)

3d 图形学的 算法，包含源代码(3d graphics algorithms, including source code)

利用matlab对彩色图像进行分割处理，图像针对bmp jpg pcn格式(color image segment)

利用固定目标和运动目标之间速度的差别所引起的多普勒频移不同根据在动目标 显示和动目标检测中使用的各种滤波器去除固定杂波提取动目标的回波能够大大 改善在杂波背景下检测运动目标的能力仿真结果显示出很好的效果也给出了改善 因子与积累脉冲数间关系 (radar moving target simulation)
