摘要：In real world, shadow causes serious problems while segmenting and extracting the foreground. Shadow can also distort the shape of object if shadow of one object is projected on another object. In some cases shadows can yield additional information regarding the scene and lighting conditions and hence can be considered desirable. So the objective is to create a system that can automatically detect shadow regions and then remove shadow from single images of natural scenes. Numbers of approaches are proposed in the literature to address such problems such as region based approach in which image is segmented into regions then classified and matting is used to recover shadow-free image. This paper is aimed to provide a survey on various methods of shadow detection and removal with their advantages and disadvantages. This paper will serve as a quick reference for the researchers working in same field.
