”AVSS” is the dataset from AVSS 2007, and ”ITEA” is the one from ITEA CANDELA. Occlu- sion is the one of major problems influent to the qualification of owner extraction. There are two major situations happen with a high frequency: (a) Passing situation: a pedestrian passes behind the owner (as shown in Fig.5 right column), (b) Part or Total occlusion: a pedestrian is occluded partly or totally by others (as shown in Fig.5 center and left column respectively). Thanks to Alg. 1, we can overcome such a situation with high accuray. Fig. 6 illustrates one case of this problem.
