Title: METHOD AND APPARATUS FOR ENCODING AND DECODING MOTION INFORMATION
Abstract:
A Frame Rate Up-Conversion (FRUC) derivation process, based on frame rate up- conversion techniques, is developed in the reference software JEM (Joint Exploration Model) by the Joint Video Exploration Team (JVET). In one embodiment, a modified FRUC derivation process improves the performance of the current FRUC tool is provided. For example, an initial list of motion vector candidates defined in the FRUC derivation process may be reordered, and/or one or more of the ordered motion vector candidates in the defined list may be removed to improve the efficiency of the process. The reordering and/or the removal may be based on, e.g., one or more of previously determined motion vector candidates of one or more previously decoded blocks. In addition, the adaptive reordering mode may be signaled by the encoder to the decoder as part of the modified FRUC derivation process.
