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 performances of the current FRUC tool is provided. For example, some candidates of a bi-predictive pair may be discarded initially, which would save signification processing time. The discarding decision may depend on various criteria such as, e.g., a ratio between matching costs of a bi-predictive pair from two reference picture lists, a difference between the matching costs of a bi-predictive pair normalized by their respective template areas.
