Scene Collages and Flexible Camera Arrays

http://www1.cs.columbia.edu/CAVE/projects/scene_collage/

In this project, we developed an approach to generating a Hockney-style collage from a set of input images, which we call a scene collage. In a scene collage, images of a scene are laid out using similarity transforms computed based on feature matching; the layer ordering of the images is determined automatically via an optimization procedure to make the collage appear least fragmented. The final collage can be displayed with opaque layers, transparent layers, or blended boundaries.

To create video collages of dynamic scenes, we present new designs of camera arrays for capturing multiple videos of a scene from different viewpoints. Our design consists of a plastic frame onto which a set of cameras can be easily attached, very much like Lego(R) building blocks. The spatial layout of the cameras can be reconfigured in a matter of minutes to achieve a variety of configurations, such as "L" and "T" shaped ones. The plastic frame can be physically flexed to vary the shape of the array. This gives a photographer significant creative control — the composition of the scene can be smoothly varied as the scene changes.
