1. A computer-implemented method for determining an occlusion cost for concurrently presenting multiple images within a shared viewing region, said method comprising: receiving image saliency data for a first image to be displayed concurrently with a second image in said shared viewing region; receiving image saliency data for said second image; receiving a layout orientation for concurrently presenting said first image and said second image within said shared viewing region; and utilizing said image saliency data for said first image and said image saliency data for said second image to determine the occlusion cost of said layout orientation for concurrently presenting said first image and said second image within said shared viewing region.
