Abstract

Se usa información para un filtro de interpolación conmutable (SIF) independientemente para particiones separadas en modo de fusión geométrica, tal como en codificación de vídeo versátil. La información de SIF puede usarse en una etapa de predicción, almacenada en un campo de modo de partición geométrico, y para definir la precisión de la resolución de vector de movimiento adaptativa de la unidad de codificación codificada por partición geométrica. En una modalidad, factores de predicción de una lista de candidatos se heredan a partir de un indicador SIF o de otros candidatos.
