Abstract

En la presente descripción se describen sistemas, dispositivos y métodos para la codificación de vectores de movimiento en el modo de fusión simétrica. Los vectores de movimiento (MV) de bipredicción (bipred) simétrica pueden construirse a partir de candidatos disponibles en una lista de candidatos para fusión para el modo de fusión de interpredicción regular y/o modo de fusión de predicción afín. Los MV candidatos para fusión disponibles pueden extenderse o mapearse simétricamente en cualquier dirección (p. ej., entre imágenes de referencia antes y después de una imagen actual), por ejemplo, cuando se codifica una imagen que permite la predicción de compensación de movimiento (MCP, por sus siglas en inglés) bidireccional. Un candidato para fusión de bipred simétrica puede seleccionarse de entre candidatos para fusión para predecir la información de movimiento de una unidad de predicción (PU) actual. La construcción de mapeo simétrico puede ser repetida por un decodificador (p. ej., basado en un índice codificado de la lista de MV candidatos para fusión), por ejemplo, para obtener los mismos candidatos para fusión y MV codificado en un codificador.
