Occlusion results to the grayscale images of varying degrees of occlusion. (a) For 10% occlusion of the encrypted image. (b) For 25% occlusion of the encrypted image. (c) For 50% occlusion of the encrypted image. (d) For 75% occlusion of the encrypted image; (e) MSE plot with the percentage of the occluded area; (f) CC plot with the percentage of occluded area.
