Abstract

Se genera una lista de candidatos de fusión, se selecciona un candidato de fusión de la lista de candidatos de fusión como un candidato de fusión, se decodifica un flujo de bits para derivar una diferencia de vector de movimiento y se deriva un candidato de fusión corregido al adicionar la diferencia de vector de movimiento a un vector de movimiento del candidato de fusión seleccionado para una primera predicción sin modificar en escala ni restar la diferencia de vector de movimiento de un vector de movimiento del candidato de fusión seleccionado para una segunda predicción sin modificación de escala.
