The recognition of shadows is an important object of research in the field of image processing. First of all in video-based traffic-state analysis, shadows cause significant disturbances. Today, shadow modelling and detection has been rather extensively examined, but there is a lack of systematisation and evaluation of basic concepts. Therefore, this paper contains a short introduction of the basic concepts and the use of these concepts in reliable methods. To get a comparative study, every method is applied to the same example images. The study points out the need for further investigation of basic technologies and applications.
