基于颜色属性的车辆阴影去除方法
VEHICLE SHADOW REMOVAL METHOD BASED ON COLOUR ATTRIBUTE
摘要
Abstract
Colour attributes,i.e.,the language colour labels,can be used to represent all the colours in the world.The colour attribute of shadow in video frames is the black,therefore we propose a colour attribute-based vehicle shadow removal method.We study the colour attrib-utes using probabilistic latent semantics model,establish colour names probability dictionary,and realise colour names mapping on video frames image.After binarisation operation,the black regions representing the shadows are set as the background,and the non-shaded regions are set as the foreground.At the same time,we process “AND”operation on the binarisation graph and background difference graph to remove shadows and then remove the noises on edges outside the shadows.Finally,we deal with the AND graph in operations of dilation first followed by connected domains filling to get the target vehicle without shadows.Experiments show that the method can remove shadows well under cer-tain scenarios,and can get a relatively intact moving vehicle target.关键词
