The results of our algorithm are shown in Figure 3. The first pair of images, Figures 3a and 3b show two camera views of an empty scene; Figure 3c is the key image at run time with the person in the view of the camera. The background is subtracted by one of the following methods (Figure 3d-f): 1) simple tolerance range , 2) simple tolerance range on a disparity map, adjusted by the refinement procedure, and 3) windowed means on a refined disparity map. Note the presense of the occlusion shadow right behind the person.
Figure 4 demonstrates the process of removing the occlusion shadow. Three camera views are shown in the top row, where Figure 4a is a left reference camera view, Figure 4b is a key camera view and Figure 4c is a right reference camera view. Figures 4d and 4e show subtraction performed on two pairs of images. Figure 4f shows the result of using all three cameras.
