Abstract

Se divulgan un método y aparato para una mejor codificación de modo intra-predicción; la intra-predicción explota la relación espacial dentro de una imagen o dentro de una región de una imagen. en la práctica, la imagen se divide en bloques y la predicción intra-modo se realiza por bloque; en sistemas de codificación nuevos, los múltiples modos intra-predicción como modo Vertical, Horizontal, modo DC y modo Diagonal se han utilizado para mejorar la eficiencia de codificación de la intra-codificación; no obstante, la información de selección de modo para intra-predicción tiene que ser transmitido al decodificador para su operación correcta; en codificación de video de alta eficiencia (HEVC), se considera un esquema de codificación para el modo de predicción intra-luma, donde el modo intra-predicción de un bloque actual se compara con el mínimo de dos modos de proedicción intra-luma correspondientes a dos bloques vecinos; si el modo intra-predicción del bloque actual es el mismo que el mínimo de los dos modos de predicción intra-luma vecinos, se transmite un solo bit para indicar el caso. de lo contrario, la información del modo intra-predicción actual se transmite en palabra código de longitud fija; aunque el esquema de codificación para el modo de predicción intra-luma considerado no puede aprovechar plenamente los modos de predicción intra-luma vecinos, es conveniente mejorar aún más el desempeño; por lo tanto, un mejor esquema de codificación para modo intra-predicción es descrito, en donde se derivan mas de un candidato de modo intra-predicción.
