針對室內(nèi)安全監(jiān)控的場景特點(diǎn),提出一種穩(wěn)健的運(yùn)動(dòng)目標(biāo)檢測方法,對每個(gè)背景像素使
用多個(gè)矢量表示,利用當(dāng)前幀和背景幀像素的色度分量差分進(jìn)行運(yùn)動(dòng)檢測,并選擇性地更新背景模型。實(shí)驗(yàn)表明,該方法能有效消除背景中振動(dòng)對象的干擾,提高運(yùn)動(dòng)目標(biāo)檢測的準(zhǔn)確性,有利于消除由于虛假目標(biāo)而導(dǎo)致的誤報(bào)警。

Abstract: According to the characteristic of the indoor surveillance, this paper presents a robust method for moving object detection, which gives multi vectors for each background pixel, and detects moving object via the chroma difference of the current and background image, at the same time the background model can be selectively updated. The experiments show this method can eliminate the swaying objects in the background and improve the detection of moving objects and reject false alarms.
