Photomosaic Generation and Representative Photomosaic Selection for Photograph Browsing

Photomosaic arranges many small photographs to represent a large image. Our study applies the photomosaic to a photograph browser CAT. Our implementation displays photomosaic while zooming out, and individual photographs while zooming in. Here, many photograph browsing software displays a set of photographs in the order of their times. To maintain this order of photographs, our photomosaic-like image generation technique firstly arranges the given set of photographs in the order of their times, and then retouches so that the set of photographs forms a photomosaic-like scene. This paper presents our technique for photomosaic generation, a user evaluation to discuss what kinds of photographs are preferable to be applied, and an automatic photomosaic selection technique.
