使用PCL库进行点云投影，朱德海《点云库PCL学习教程》第二章示例代码(Example code for Lidar cloud data projection)

中值滤波在图像处理中占据很重要的地位，本代码是加权中值滤波处理源码。希望对大家有用。(Median filter in image processing occupies a very important position, the code is weighted median filter processing source. Hope to be useful.)

说明：  MATLAB读取envi的raw格式高光剖数据(Matlab reading the raw data of envi)

演示了点阵字符的绘制方法，visual c++源码(Demonstrates a dot matrix characters drawing method, c++ source code)

基于AdaBoost的人脸检测程序代码(是用c++编写的)(AdaBoost-based face detection program code (written with c++))

此demo演示的是一个能够检测并跟踪道路上的标记线并且在适当时机发出报警的系统，此系统可使汽车在行驶过程中能够避免偏离车道。系统由一台摄像机，一台计算机，以及一个扬声器组成，摄像机采集视频信息交由计算机处理，根据处理结果控制扬声器是否报警。(This demo demonstrates a system that detects and tracks the marking lines on the road and sends out the alarm at the right time, which enables the car to avoid deviating from the driveway during the driving process. The system is composed of a camera, a computer, and a loudspeaker. The video information is processed by the camera to control the alarm of the speaker according to the processing results.)

利用蝶形算法类似于FFT，利用先行再列实现二维DCT。速度很快。包含反DCT的代码。(similar to the use of butterfly FFT algorithm, the first re-use of 2D DCT out. Very fast. Contain anti- DCT code.)

说明：  基于surf算法的复制移动检测，此方法适合图像伪造研究者初级实验(Replication mobile detection based on surf algorithm)

使用马尔可夫随机场进行图像分割，包括标记场、特征场建模和参数估计等，程序可运行。(image segmentation Using Markov random field , including label Field, features field modeling and parameter estimation, the program can run.)

粒子滤波器（particle filter）程序，用粒子滤波器跟踪运动物体。(Particle filter (particle filter) process, with particle filter to track moving objects.)
