Adding geometrical terms to shadow detection process

The elimination of strong shadow in outdoor scenes containing human activity is addressed in the paper. The main contribution of the introduced method is the integration of geometrical information into the shadow detection process. This novel approach takes into account the collinearity of shadow and light direction and completed with a simple colour based pre-filtering. The final classification step is carried out via a Bayesian iteration scheme which is general enough to handle further characteristics of the problem: weak shadow and reflection.
