【正文】 Abstract Motion target detection is one of the main issues in puter vision, which bines advanced technologies in image processing, Pattern recognition, automatic control, artificial intelligence, puter and other relative fields. It has broadly applied in military visual missile guidance, video surveillance, medical image analysis, intelligent transportation and other fields, so this project research has important theoretical significance and practical value. Based on the summary and analysis of the current detecting moving objects methods, this paper has designed and implemented an experiment which can detect moving object in image sequence after captured, using the detecting algorithm of realtime for video, which obtain a better experimental result. In the collection of images, the existed AVI video taken by myself has been adopted in this paper and transformed properly. In that way, it can facilitate the reading and transformation of MATLAB. In the process of object detection, this paper also offers simple background and plex background for object detection. In terms of these two AVI videos, detection to the AVI video via utilizing background subtraction and the improved background subtraction, to some extent, can enhance the parability of the experimental Characteristics including object positions and so on, given by the operation of this experiment have enhanced the intuitiveness of the experiment. The experimental result shows that the detecting algorithm used in this system attain the expectable purpose. The algorithm and methods used in this paper will be valued either in the domain of intelligent video control, air surveillance, and industrial detection and so on. Keywords: intelligent monitoring, moving object detection, background subtraction, background extraction, feature matching i 目 錄 摘要 Abstract 第一章 緒論 .................................................................................................................. 1 課題研究背景及意義 ..................................................................................... 1 國內(nèi)外研究現(xiàn)狀 ............................................................................................. 2 論文內(nèi)容及組織安排 ..................................................................................... 3 第二章 運動目標檢測有關(guān)的理論基礎(chǔ) ...................................................................... 4 數(shù)字圖像基本 概念 ......................................................................................... 4 圖像灰度變換 ................................................................................................. 5 中值濾波 ......................................................................................................... 6 邊緣檢測 ......................................................................................................... 6 圖像配準 ......................................................................................................... 7 運動目標檢測技術(shù) ......................................................................................... 7 幀間差分法 ........................................................................................... 7 背景差分法 ........................................................................................... 8 光流法 ................................................................................................... 8 統(tǒng)計學法 ............................................................................................... 8 第三章 運動目標檢測設(shè)計分 析 ................................................................................ 10 總體設(shè)計思路 ............................................................................................... 10 背景差分法 ................................................................................................... 10 總體設(shè)計流程圖 ................................................................................ 10 功能模塊的分析 ................................................................................ 11 改進的背景差分法 ....................................................................................... 12 總體設(shè)計流程圖 ................................................................................ 12 功能模塊的分析 ................................................................................ 12 第四章 運動目標檢測實驗驗證與結(jié)果分析 ............................................................ 15 運動目標檢測實驗介紹 ............................................................................... 15 簡單背景視頻 ............................................................................................... 15 ii 背景差分法實現(xiàn) ................................................................................ 15 改進的背景差分法實現(xiàn) .................................................................... 17 復雜背景視頻 ............................................................................................... 18 背景差分法實現(xiàn) ................................................................................ 18 改進的背景差分法實現(xiàn) .................................................................... 20 結(jié)果分析 ....................................................................................................... 21 第五章 總結(jié)與展望 .................................................................................................... 23 研究總結(jié) ....................................................................................................... 23 研究展望 ....................................................................................................... 24 參考文獻 ...................................................................................................................... 25 致謝 .............................................................................................................................. 27 附錄 簡單背景視頻和復雜背景視頻核心程序 ........................................................ 28 簡單背景視頻和復雜背景視頻核心程序的簡單介紹 ............................... 28 簡單背景視頻的背景差分法核
