Abstract

Un método para codificar valores de color pixel para una estructura de imagen de digital de video en el cual se le asigna un valor de color a cadadiferente color dentro de la imagen. Un color predominante es identificado para la estructura deim agen y, en una primera realización, cada pixel que tenga uncolor que no sea el color predominante es codificado separadamente como su respectivo valor de color (0010 a 1111), siendo codificados según largo decorrida las corridas de tres omás pi xels sucesivos del color predominante. Se provee otro código más (0000 0011 cccc), similar en disposición a aquel queindica una corrida, para permitir un cambio en el color predominante especificado durante el curso de unaestructura. En otra realización, lascorridas de todos los colores son codificadas a lo largo de todas las corridas pero con un esquema de código más corto para corridas del color predominante o,en aun otra realización, en un pequeno rango decolores predominantes. El principal uso de estos esquemas de codificación es para mejorar la eficienciade codificación de ciertas clases de material de imagen.
