We design 5 experiments, with two types of occlusions: (1) 3 experiments are about salt and pepper occlusion, where we randomly place 3 × 3 masks on the 64 × 64 image domain to cover 50%, 70% and 90% of pixels respectively. These 3 experiments are denoted P.5, P.7, and P.9 respectively (P for pepper). (2) 2 experiments are about single region mask occlusion, where we place a 20 × 20 or 30 × 30 mask on the 64 × 64 image domain.
