Abstract
An integrated system and method for content-aware video retargeting. An interactive framework combines key frame-based constraint editing with numerous automatic algorithms for video analysis. This combination gives content producers a high level of control of the retargeting process. One component of the framework is a non-uniform, pixel-accurate warp to the target resolution that considers automatic as well as interactively-defined features. Automatic features comprise video saliency, edge preservation at the pixel resolution, and scene cut detection to enforce bilateral temporal coherence. Additional high level constraints can be added by the producer to achieve a consistent scene composition across arbitrary output formats. Advantageously, embodiments of the invention provide a better visual result for retargeted video when compared to using conventional techniques.
