Shadow Detection Algorithm Based on Edge Information and Illumination Direction

This paper proposes a shadow detection algorithm based on edge information and illumination direction.It detects shadow which unifies through the shadow characteristics of HSV and RGB color space,estimates the illumination direction through the shadow which formerly examined,and uses the shadow detection algorithm based on edge information to detect the shadow in the threshold range of illumination direction.It can effectively detect the shadow of a moving object and remove the shadow disturbance for the following processing.Experimental results show that the algorithm is robust to noise and more efficient than traditional algorithms.
