Abstract
The recent spread of low-cost, high-performance digital cameras and smartphones allows us to share a large-scale imagery data on the Web. However, most of such images were taken subjectively in terms of composition and chosen targets. This article presents an ambient visualization system which makes up for the semi-structured properties of still images so that the users can comprehend the surrounding environment as well as photographed objects in an objective manner. To that end, the proposed system organizes a collection of input images is into a tree-of-graph structure called abstraction hierarchy, and provides the users with two specific types of view transformation, i.e., vertical view scaling and horizontal view scrolling.
