International Symposium on VIPromCom Video/Image Processing and …, 2002•ieeexplore.ieee.orgA new approach for real-time shadow detection and elimination is presented. In contrast to
existing methods, hue and saturation is approximated in the YUV-colour space straight
away. We show the linear influence of shadow to the YUV-values and exploit this behaviour
in a fast decision scheme. The proposed method is robust and capable for real-time video
processing without any need of colour space transformations.
