摘要： A video sequence having a plurality of frames is received. A feature in a first frame from the plurality of frames and a first position of the feature in the first frame are detected. The position of the feature in a second frame from the plurality of frames is estimated to determine a second position. A displacement vector between the first position and the second position is also computed. A plurality of content characteristics is determined for the first frame and the second frame. The displacement vector is spatially diffused with a spatial filter over a frame from the plurality of frames to generate a spatially diffused displacement vector field. The spatial filter utilizes the plurality of content characteristics. A temporal filter temporally diffuses over a video volume the spatially diffused displacement vector field to generate a spatiotemporal vector field. The temporal filter utilizes the plurality of content characteristics.

摘要： Techniques are provided 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.

摘要： Systems, methods and articles of manufacture are disclosed for performing scalable video coding. In one embodiment, non-linear functions are used to predict source video data using retargeted video data. Differences may be determined between the predicted video data and the source video data.
