Abstract

Se proporciona un método y aparato de codificación de video y un método y aparato de decodificación de video para producir un video reconstruido que tiene un error mínimo con respecto a un video original. El método de decodificación de video incluye analizar un parámetro de corrección de borde a partir de un flujo de bits, el parámetro de corrección de borde se utiliza para corregir un pixel reconstruido incluido en un bloque actual, determinar si el pixel reconstruido está incluido en una región de borde de conformidad con un primer valor umbral incluido en el parámetro de corrección de borde, determinar si el pixel reconstruido va a ser corregido de conformidad con un segundo valor umbral incluido en el parámetro de corrección de borde cuando el pixel reconstruido está incluido en la región de borde, y compensar un valor de muestra del pixel reconstruido de conformidad con un tercer valor umbral incluido en el parámetro de corrección de borde cuando se va a corregir el pixel reconstruido.
