Description: 智能交通监视系统中基于边缘的运动目标提取算法
本文的算法是基于C++和OPEN CV实现的，要运行此程序首先要安装这两个软件
由于本文在采集图像时用到的视频图像较大 ，要100多兆，所以演示程序采用另一个视频，以观其效果
本程序中采用视频序列的前四十帧的奇数帧提取出背景边缘，用参数backframes来控制，backframes/2
即是采用的帧数。
cedge_thresh1和cedge_thresh2来控制做背景检测是用到的CANNY算子的两个阈值。
edgesum_thresh控制来背景边缘提取时去掉运动目标边缘的阈值。
-Intelligent traffic monitoring system based on the edge of the moving object extraction algorithm of this article is based on the algorithm C++ And OPEN CV achieved, it is necessary to run this program first to install these two software as a result of this paper used in the acquisition of images of the video image more large, to more than 100 megabytes, so the use of another video demo program to view the effect of the procedure used in video sequences of the first 40 odd-numbered frames to extract the background of the edge of backframes using parameters to control, backframes/2 that is used the frames. cedge_thresh1 and cedge_thresh2 to control the background detection is the Canny operator to use two thresholds. edgesum_thresh control to the background when the edge detection of moving targets to remove the edge threshold.

Description: 基于编码TMS320DM642的MPEG4编码器设计与实现。为满足视频通信中视频压缩的需要，在对MPEG4视频编码标准研究的基础上，提出了基于TMs32ODM642
DSP的MPEG4视频编码器的实现方案，并讨论了代码优化的方法，通过相关实验对提出的方案进行了编验证。实验结果表明，该方案实现了对标准QCIF格式图像序列的MPEG4编码，编码速率达到25 fps，满足了实时码的要求，图像质量满足
了预期效果。-TMS320DM642-based encoding of the MPEG4 Encoder Design and Implementation. Video communications in order to meet the needs of video compression, in the MPEG4 video coding standard based on the research, TMs32ODM642DSP based on the MPEG4 video encoder realization of the program and discuss ways to optimize the code, through the relevant experimental program conducted on the proposed the provision of authentication. Experimental results show that the program achieved the standard QCIF format MPEG4 image sequence coding, coding rate reached 25 fps, to meet the requirements of real-time code, the image quality to meet the desired effect.

Description: pHash is an implementation of various perceptual hashing algorithms. A perceptual hash is a fingerprint of an audio, video, or image file that is mathematically based on the audio or visual content contained within. Unlike cryptographic hash functions that rely on the avalanche effect of small changes in input leading to drastic changes in the output, perceptual hashes are "close" to one another if the inputs are visually or auditorily similar. As a result, perceptual hashes must also be robust enough to take into account transformations that could have been performed on the input.
