摘要

Background subtraction algorithm is susceptible to both global and local illumination changes such as shadows, sunlight, and reflection. These changes sometimes cause failures in object tracking, gesture recognition, or posture estimation. In this chapter, we propose a method for detecting objects casting shadows in an indoor scene by modeling a pixel value as the total energy received from light sources. Our proposed method can also estimate the rate of illumination change in order to improve background subtraction. Experimental results demonstrate the usefulness and performance of the method.
