An animation collage is a complete reassembly of the original animation in a new abstract visual style that imitates the spatio-temporal shape and deformation of the input. Our algorithm automatically decomposes input animations into plausible approximately rigid segments and fits to each segment one shape from the database by means of a spatio-temporal matching procedure. The collage is then animated in compliance with the original s shape and motion. Apart from proposing solutions to a number of spatio-temporal alignment problems, this work is an interesting add-on to the graphics artist s toolbox with many applications in arts, non-photorealistic rendering, and animated movie productions. We exemplify the beauty of animation collages by showing results created with our software prototype.Categories and Subject Descriptors (according to ACM CCS): J.5 [Arts and Humanities]: Fine arts I.3.7 [3D Graphics and Realism]: Animation I.3.5 [Computational Geometry and Object Modeling]: Geometric algorithms
