From: Jared Sherman "Photoshop and other image processing software all does this as standard today. Post-processing to generate sharpness in excess of the image sensor's ability is standard today. We know the job can be done in software. So, why shouldn't a processor like the human brain also be able to run a similar program?" Apparent 'sharpness' only is improved by such software - not resolution - by increasing the contrast (making dark edges darker, light edges lighter) where the edge of one shape abuts another. As to whether the brain can do something similar I don't know, but it's a fascinating idea.
