減背景技術(shù)是一種常用的運動對象檢測方法，其基本思想是將視頻中當前幀圖象與事先存儲的或?qū)崟r得到的背景模型相減，通過閾值操作，得出運動區(qū)域。 - a statistical method is used to obtain the background model, which is updated real time in order to adapt to illumination changes and scene changes . after threshold operation, morphologic operation and connected region area measurement are introduced to solve background disturb problem . at last, shadows are detected using hsv color space information and gets exact moving regions
該方法首先利用統(tǒng)計的方法得到背景模型，并實時地對背景模型進行更新，以適應(yīng)外界光線變化和場景本身的變化，閾值操作后，用形態(tài)學和連通域檢測的方法進行后處理，消除噪聲和背景擾動帶來的影響，最后，在hsv顏色空間下檢測出陰影，得到準確的運動對象區(qū)域。 - It's difficult to find threshold operations in a sentence. 用threshold operations造句挺難的
