Identifying Computer-Generated Portraits: The Importance of Training and Incentives.

abstract：:A novel approach to the question of image segmentation is considered. Instead of relying on edge-detection mechanisms to encircle the image of an object, it is proposed that the general Gestalt-like properties of images of objects can be used. These manifest themselves as particularly simple properties at relatively c...
