Although people in the 20th century has been proposed many effective moving target tracking algorithm, but in fact, moving target tracking technology is still in the process of realization is difficult, such as unstable background, target tracking process is blocked, the target the background color is similar with other factors, will largely destroyed tracking results, therefore, in order to design a good effect mean shift tracking algorithm still has a great challenge. In this paper, a brief introduction about the history of the moving target tracking technology ( from the first to be made until the technology applied to various fields ), moving target tracking technology has gone through a long process. The paper also mentioned the structural frame of video surveillance systems, and analysis of the principle of each part。 also studied image processing technology in intelligent video surveillance system consists mainly of mathematical morphology theory, image preprocessing and objectives model description. For the application of intelligent video surveillance system in practice, this thesis is the MeanShift (mean shift) tracking algorithm, which is an advanced motion tracking technology. Also a detailed analysis based on the mean shift algorithm in moving target tracking application, and verify the MeanShift algorithm in the practical application of the convergence [1]. For the mean shift algorithm prone shortings, its one break, and conducted a number of simulations, the conclusions show that : better tracking performance of the algorithm. Keywords : intelligent video surveillance。 video image processing。 background subtraction。 tracking of moving targets。 MeanShift algorithm 湖南工學(xué)院(本科)畢業(yè)設(shè)計(jì)論文 目 錄 1 緒論 ...................................................................1 課題研究背景與意義 ...............................................1 國(guó)內(nèi)外研究現(xiàn)狀 ...................................................1 目標(biāo)跟蹤問(wèn)題的困擾因素 ...........................................2 本章小結(jié) .........................................................3 2 圖像處理簡(jiǎn)介 ...........................................................4 圖像灰度化處理 ...................................................4 圖像噪聲處理 .....................................................4 目標(biāo)表示 .........................................................5 數(shù)學(xué)形態(tài)學(xué) .......................................................6 本章小結(jié) .........................................................7 3 VC 編程環(huán)境的搭建 ......................................................8 OpenCV 簡(jiǎn)介 ......................................................8 下載和安裝 OpenCV .................................................8 搭建 OpenCV 環(huán)境 ..................................................8 OpenCV 中常用函數(shù)介紹 ...........................................10 數(shù)據(jù)結(jié)構(gòu) ..................................................10 常用函數(shù) ..................................................12 本章小結(jié) ........................................................14 4 基于 MeanShift 的目標(biāo)跟蹤算法 .........................................15 運(yùn)動(dòng)目標(biāo)跟蹤綜述 ................................................15 MeanShift 算法研究 .............................................15 基本 MeanShift 算法 .......................................15 MeanShift 算法工作原理分析 ...............................16 程序運(yùn)行結(jié)果 ....................................................19 圖形界面 ..................................................19 目標(biāo)跟蹤效果 ..............................................20 本章小結(jié) ........................................................22 結(jié)束語(yǔ) ..................................................................23 湖南工學(xué)院(本科)畢業(yè)設(shè)計(jì)說(shuō)明書(shū) 參考文獻(xiàn) ................................................................24 致 謝 ...................................................................25 附 錄 ...................................................................26 湖南工學(xué)院(本科)畢業(yè)設(shè)計(jì)論文 1 1 緒論 課題研究背景與意義 運(yùn)動(dòng)目標(biāo)跟蹤技術(shù)是計(jì)算機(jī)視覺(jué)領(lǐng)域的核心研究課題之一,它涉及到各個(gè)科研領(lǐng)域。隨著社會(huì)的快速發(fā)展,光靠人力已經(jīng)無(wú)法實(shí)現(xiàn)對(duì)龐大的數(shù)據(jù)進(jìn)行分析、處理。因此,急需一項(xiàng)技術(shù)能夠代替人在不穩(wěn)定的環(huán)境中對(duì)繁瑣的數(shù)據(jù)的進(jìn)行處理。智能視頻監(jiān)控系統(tǒng)恰好具備這項(xiàng)功能,它通過(guò)對(duì)攝像機(jī)拍錄的圖像序列進(jìn)行自動(dòng)分析,實(shí)現(xiàn)對(duì)動(dòng)態(tài)場(chǎng)景中目標(biāo)定位、識(shí)別與跟蹤 【 2】 。本論文主要是對(duì) MeanShift 目標(biāo)跟蹤算法進(jìn) 行研究。 通過(guò)研究者們的實(shí)踐發(fā)現(xiàn), MeanShift 算法 在運(yùn)動(dòng)目標(biāo)跟蹤領(lǐng)域中有著相當(dāng)高的目標(biāo)匹配度 , 多次應(yīng)用在了對(duì)實(shí)時(shí)性要求高的運(yùn)動(dòng)目標(biāo)跟蹤技術(shù)中。 MeanShift 算 法不僅在軍事領(lǐng)域舉足輕重,工業(yè)領(lǐng)
