Abstract

Se proporciona un método y un aparato para codificación y decodificación de imágenes a través de inter-predicción. El método de decodificación incluye: determinar información de movimiento de predicción de un primer bloque de decodificación; llevar a cabo predicción bidireccional en el primer bloque de decodificación con base en la información de movimiento de predicción para obtener un primer bloque de predicción de decodificación; llevar a cabo búsqueda de movimiento de primera precisión en un bloque de imagen de referencia de predicción para obtener al menos un segundo bloque de predicción de decodificación, donde una ubicación de búsqueda de la búsqueda de movimiento se determina al utilizar un predictor de vector de movimiento y la primera precisión; calcular una diferencia entre el primer bloque de predicción de decodificación y cada segundo bloque de predicción de decodificación para obtener un predictor de vector de movimiento objetivo del primer bloque de decodificación; y actualizar el predictor de vector de movimiento objetivo a través de búsqueda de movimiento. Por lo tanto, se mejora precisión de inter-predicción.
