A computational approach to stylizing and
abstracting photographs based on a model of
human perception
Why ? - Clarifying the meaningful visual
structures How to identify them ? -
Representing an image as a hierarchy of visual
parts and boundaries - Employing a model
of human perception guided by an eye
tracker How to represent (abstract) them ? -
NPR !!! - In particular, bold edges and large
regions of constant color to preserve and
highlight the visual elements
