Methods And Apparatus For Implicit Adaptive Motion Vector Predictor Selection For Video Encoding And Decoding
Patent No. EP2548372 (titled "Methods And Apparatus For Implicit Adaptive Motion Vector Predictor Selection For Video Encoding And Decoding") was filed by Interdigital Madison on Mar 3, 2011. The application was issued on Feb 15, 2023.
Patent Summary
Implicit adaptive motion vector predictor selection for video encoding and decoding that improves motion estimation accuracy without additional overhead compared to explicit motion vector prediction methods. The prediction is based on the motion vectors of spatio-temporal neighboring blocks, and the selection is implicitly derived from their prediction confidence metrics rather than explicitly transmitted. This leverages correlation between nearby blocks without additional communication. The encoder predicts the motion vector for a block by selecting from the set of neighboring motion vectors based on their fidelity metrics. The decoder derives the motion vector by exploiting the correlation of the neighboring vectors.
