摘要运动视频中的目标检测是计算机视觉和图像处理领域里一个相当重要的课题，在实际生活中，许多有用信息包含在运动的目标中，因此将其快速分离是对图像后续分析处理的关键操作。目前已经被成熟的运用在国防和国民经济建设等领域中，而且其应用范围还在不断增加。人们在实际生活中，对某一场景的长时间监控常采用摄像机，而对目标的检测和识别是靠人来完成的，这个具有非常不稳定的确定因素和高昂的成本，因此运动目标检测的理论的实现是具有现实意义的。围绕这个检测理论，人们做出了大量有意义的工作，由于其潜在的应用前景已经成为了目前视觉处理界研究者们工作的热点之一。28143
本文首先介绍了图像预处理的相关内容及运动目标检测的相关检测技术，分析了两种运动目标检测的算法。在此基础之上，使用Matlab软件进行算法仿真实验，初步实现了背景差分法和帧间差分两种运动目标检测算法。

Title The detection algorithm of moving target in monitoring system
Abstract
Motion video object detection computer vision and image processing in a very important issue, in real life, a lot of useful information contained in the objectives of the campaign, so be quick separation is the key operation for subsequent image analysis and processing. Has now been established in the field of national defense and the use of the national economy and the like, and its scope of application is growing. People in real life, prolonged monitoring of a scene often used cameras, while the target detection and recognition is done by people, and this has a very unstable determining factors and high costs, thus moving object detection realization theory is of practical significance. Around this detection theory, people make a lot of meaningful work, because of its potential applications have become one of the hot visual processing sector researchers work.
This paper introduces the image pre-processing and correlation detection technology related content moving target detection and analysis of the two moving target detection algorithms. On this basis, the use of Matlab software simulation algorithm, the initial realization of background subtraction and frame difference two sports target detection algorithms.
Keywords Image processing The way of background difference The way of background difference MATLAB
