Make a Scene Collage

You can create a collage of a scene by taking several overlapping photos and running them through a program called AutoSceneCollage.   This tool was developed by Yoshi Nomura, Li Zhang and Shree Nayar at the Computer Vision Laboratory, Columbia University, New York.   The scene collages produced by this tool are similar in appearance to the photographic collages created by the Bristish artist David Hockney.   You can download AutoSceneCollage from here.
