Abstract :
A 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.
