Abstract

Se describen un método de codificación de video y un método de decodificación de video que usan ajuste de desplazamiento con base en la clasificación de pixel de cada unidad de codificación más grande (LCU). El método de codificación de video incluye determinar un parámetro de desplazamiento de cada LCU, el parámetro de desplazamiento incluye un tipo de desplazamiento que indica si un método de clasificación de valores de pixel de una LCU actual es un tipo de borde o un tipo de banda, una clase de desplazamiento que indica una dirección de borde o un rango de banda, y un valor de desplazamiento que indica un valor de diferencia entre los pixeles reconstruidos y pixeles originales; y emitir información de unificación de desplazamiento que indique si se debe adoptar un parámetro de desplazamiento de una LCU a la izquierda o superior de la LCU actual como el parámetro de desplazamiento de la LCU actual.
