Abstract

Se describen técnicas para codificación basada en paleta; en la codificación basada en paleta, un codificador de video puede formar una paleta como una tabla de colores para representar datos de video de un bloque determinado; la codificación basada en paleta puede ser útil para codificar bloques de datos de video que tienen un numero de colores relativamente pequeño; en lugar de codificar valores de pixel reales o sus residuales para el bloque determinado, el codificador de video puede codificar valores de índice para uno o más de los pixeles; los valores de índice mapean los pixeles a entradas en la paleta que representan los colores de los pixeles; se describen técnicas para determinar si se inhabilita la filtración, tal como la filtración de desbloqueo o filtración de compensación de muestra adaptable (SAO), de los bloques codificados de paleta en un codificador de video o un decodificador de video; también se describen técnicas para modificar un tamaño de paleta y entradas de paleta de una paleta en el codificador de video con base en los costos de velocidad-distorsión.
