用yolo算法检测到的视频目标，用kalman滤波算法进行多目标跟踪，程序需修改一些路径。(Yolo algorithm is used to detect video targets, Kalman filtering algorithm is used to track multiple targets, and the program needs to modify some paths.)

经典的Tarel去雾算法，可用于图像去雾的指标性能对比。(It is the classical dehazing algorithm, and it is can be used comparison with other algorithms.)

单目标定很好用的程序，对于单目摄像机的一个标定。张正友博士的方法，对于摄像机标定，切记标定板不能用手机拍摄，因为手机拍摄是变焦的(Single objective of the program is very good, for a single camera calibration. Dr. Zhang Zhengyou s method for camera calibration, remember that the camera calibration board can not be used to shoot the phone, because the phone is to shoot a zoom )

用arnold变换对lena图进行图像置乱(scramble a picture by arnold transformation)

图像巴特沃斯陷波器，实现了简单的巴特沃斯陷波器滤除图像的某些频率的干扰(Image Butterworth notch filter, to achieve a simple Butterworth notch filter to filter out images of certain frequency interference)

说明：  pcnn的matlab实现，pcnn神经网络主要用于图像去噪分割等(the realization of the matlab PCNN, pcnn neural network used mainly for segmentation, such as image denoising)

机动目标跟踪，交互式多模型算法的代码，一个简单的例子(Maneuvering target tracking, interactive multiple model algorithm code, a simple example)

说明：  实现了计算机全息图制作和再现，而且再现图片效果良好(A value of two LohmanIII coded images detour phase hologram, by testing the normal operation. The result with image, hologram, and reproducing figure three part.)
