...quality.

From our experience, about 70% of all generated Random Artimages are aesthetically interesting and are therefore suited for usage in Déjà Vu. The remaining 30% are either too simplistic or fall into a class of images which are frequently generated and visually similar. Since we desire visually distinguishable images in the portfolio and the decoy set, we currently filter out weak images through hand selection.
