摘要： A motion estimation method and apparatus for video coding of a multi-view sequence is described. In one embodiment, a motion estimation method includes identifying one or more pixels in a first frame of a multi-view video sequence, and constraining a search range associated with a second frame of the multi-view video sequence based on an indication of a desired correlation between efficient coding and semantic accuracy. The semantic accuracy relies on use of geometric configurations of cameras capturing the multi-view video sequence. The method further includes searching the second frame within the constrained search range for a match of the pixels identified in the first frame.

摘要： A method and apparatus for encoding video frames is described. In one embodiment, an encoding method includes jointly transforming a set of pixels into high-pass data using an orthonormal transform. The set of pixels includes at least one reference pixel and predicted pixels. The method further includes generating low-pass data using the reference pixel and the high-pass data.

摘要： Graphs representing multimedia content are validated and modified through graph matching and graph rewriting techniques using pre-defined model graphs. In one aspect, an input graph is validated against a model template graph. In another aspect, suggestions for modifying an input graph are provided based on model alphabet, rule and morphism graphs. The resulting graphs may represent queries against existing description schemes or new description schemes.
