Optical flow field contains not only the moving information of the object , but also three - dimensional information . this paper integrates the inter - frame difference and optical flow methods . the method of inter - frame difference is used to separate moving area from the whole image 本文将二者相结合,运动目标的第一步检测由帧间差值法完成,同时运用数学形态学方法对差值图像进行过滤和排查,精确提取出多运动目标的运动区域。
Hello , i also am a phthisical patient , heal also is almost 4 years , best method is : pay close attention to oneself body state at any time , go to a hospital every year doing single censoring , have the food and drink below much recuperation , move more , much breath issues fresh air 你好，我也是个肺结核患者，痊愈差不多也是四年了，最好的方法是：随时关注自己的身体状况，每年去医院做一次检查，有多调理下饮食，多运动，多呼吸下新鲜空气。
The keystone state games , modeled after the olympic games , are annually held multi - sport competitions providing pennsylvania ' s amateur athletes an opportunity to compete against athletes from throughout the commonwealth in the summer games , winter sports festival , and the pennsylvania senior games 重点州的比赛，在奥运会以后当模特儿，是提供宾夕法尼亚的业余运动员的每年保持的多运动比赛在夏天比赛，冬季运动节日，和宾夕法尼亚四年级生从在整个共同体对运动员竞争的一个机会比赛。
On the foundation of past research , author put forward a single - object tracking and detection algorithm based on background subtraction algorithm and a multi - object cooperative tracking and detection algorithm based on three layers dynamic interaction system , to implement credible unmanned active - scene detection and consecutive , real - time , concerted multiple active object tracking 在前人研究的基础上,引入了基于背景差分算法的单目标入侵检测及跟踪算法和基于三层动态交互体系的多目标协调跟踪算法,真正实现在无人状态下对运动场景进行可靠的监控,对多运动目标进行连续、实时、协调的跟踪。
Dsps is used to accurately detect the moving area of multi - moving objects and information of their geometrical position in the system , at the same time , it pick up the parameters of geometrical feature , gray feature and planar velocity of each area , at last , we integrate the techniques of multi - moving objects detection and construct a self - adapted system to track multi - moving objects . the camera is controlled to keep the object in its field of view . therefore we achieve a real time system to track the multi - moving objects in the complex scenes 本系统利用dsps精确检测出多运动目标的运动区域及其几何位置信息,并对各个运动区域进行几何特征参数、灰度特征参数和运动速度参数的提取,最后根据这些特征参数值结合多目标运动状态检测技术构建了多运动目标自适应跟踪系统,并根据已经计算出的运动目标的速度矢量,通过云台装置控制摄像头的转动,使得特定运动目标始终位于摄像机的视野中,从而完成对复杂背景中多个运动目标中特定目标的实时跟踪。
In low level , study the structure of arithmetic , the problems that may appear in real application and effect of arithmetic such as yawp and error check elimination , dealing synchronously with multi moving body , reducing the data needed disposal with reason . in high lever , based on knowledge of artificial intelligence and research in this field , bring forward identification way based on rule . what ' s more , build an extendable antetype of intelligence supervision and control system and realize some simple check and identification function that is the basement of further research 本文研究了基本的智能监控系统应具备功能的软件算法，在低层处理算法方面，研究了算法的结构，并针对实际应用中可能出现的问题及算法的时效性等方面进行研究，如对噪声、错误检测的排除、多运动对象的同时处理及合理缩减需处理的信息量等；高层算法方面，基于人工智能的知识和国外该方面的研究，提出了基于规则的事件识别方法；此外，还建立了可扩展的智能监控原型系统，实现了一些简单的检测识别功能，可作为未来的更深入的研究开发的基础；最后本文对原型系统今后如何发展为更为完善和强大的智能场景监控系统提出了若干建议。
