We examine twelve known color similarity measures with regard to their effectiveness for the background-frame differencing task. The RGB sensor space and the CIE L*a*b* color space is used to represent color. Based on experiments conducted on twelve different scenes (indoor
as well as outdoor scenes under various lighting conditions and photographed with two different types of CCD cameras) we show that the
