Blow-up: a free lunch?

Abstract

We consider operations that change the size of images, either shrinks or blow-ups. Image processing offers numerous possibilities, put at everyone's disposal with such computer programs as Adobe Photoshop. We consider a different class of operations, aimed at immediate visual awareness, rather than pixel arrays. We demonstrate cases of blow-ups that do not sacrifice apparent resolution. This apparent information gain is due to "amodal occlusion."

Keywords: amodal occlusion; image structure; occlusion; visual awareness; visual grouping; visual space.
