頻序列進(jìn)行處理,提取出視頻序列中的運(yùn)動(dòng)物體,為接下來(lái)的運(yùn)動(dòng)目標(biāo)跟蹤、運(yùn)動(dòng)行為分析等部分提供數(shù)據(jù)支持。因此如何在復(fù)雜的監(jiān)控場(chǎng)景中檢測(cè)運(yùn)動(dòng)目標(biāo)是一個(gè)比較困難的問(wèn)題。該方法將當(dāng)前視頻序列圖片分割成多個(gè)大小一定的區(qū)域,并統(tǒng)計(jì)區(qū)域中用Epanechnikov核函數(shù)對(duì)灰度分布進(jìn)行空間加權(quán)的直方圖,我們稱為距離灰度直方圖,其中利用每個(gè)區(qū)域中各個(gè)像素點(diǎn)到該區(qū)域中心的距離歸一化后作為Epan...【英文摘要】With the development of the network munication technology, microelectronics,artificial intelligence and puter vision technology, people pay more attention to theresearch and application of the intelligent security systems.
