Abstract

UN DISPOSITIVO DE CODIFICACION Y DECODIFICACION PARA UNA IMAGEN DE VARIACION TEMPORAL, MEDIANTE EL CUAL SE OBTIENE UNA GRAN CALIDAD DE LA IMAGEN A PARTIR DE UNA CANTIDAD DE INFORMACION MENOR DE LA QUE SE DISPONE EN UN SISTEMA QUE SOLO UTILIZA UNA CODIFICACION DCT. SE PUEDE MEJORAR LA EFICIENCIA DE LA CODIFICACION Y SE REDUCE DISTORSION DE LOS BLOQUES DE UNA IMAGEN COMPUESTA. UNA IMAGEN SE DIVIDE EN VARIOS BLOQUES Y SE CODIFICA CADA UNO DE LOS BLOQUES. EN ESE MOMENTO, UNA CODIFICACION DE TRANSFORMACION DEL COSENO DISCRETA (DCT) Y UNA COMPOSICION PREDICTIVA ENTRE BLOQUES (NTC) SE CONMUTAN ENTRE SI DE MANERA ADECUADA SEGUN LAS CARACTERISTICAS DEL MODELO DE LA IMAGEN. CUANDO SE EJECUTA LA COMPOSICION PREDICTIVA ENTRE BLOQUES, SE TRANSMITEN EL VALOR PREDICTIVO Y LA EXTENSION DE LA CUANTIFICACION DE UN BLOQUE.
