From: Spatio-temporal silhouette sequence reconstruction for gait recognition against occlusion
Example of simulated occlusion for a subject. The left-hand side of the figure: labels for the occlusion pattern, where the first term indicates the type of occlusion and the second term shows the degree of occlusion. The occluded area is gray only for visualization purposes; in the experiment, we masked the occluded area with black, namely the values of the masked area are set to zero; this value is the same for the background
