Photomosaic Generation for Photograph Collection Browsing

Abstract

A Photomosaic arranges many small photographs to represent a large image. Our study applies the photomosaics to a photograph browser CAT. Our implementation displays photomosaics 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 generation technique firstly arranges the given set of photographs in the order of those times, and then retouches so that the set of photographs forms a photomosaic-like scene. This paper presents our technique for photomosaic generation, and a user evaluation to discuss what kinds of photographs are preferable to be applied. We think this discussion should be fruitful for our future development of automatic photograph selection for photomosaic generation.
