Abstract

UN METODO DE COMPRESION DE DATOS POR EL CUAL DATOS DE IMAGEN QUE INCLUYEN DATOS EN COLOR PUEDEN SER COMPRIMIDOS EFICAZMENTE, Y UN METODO DE EXPANSION DE DATOS COMPRIMIDOS POR EL CUAL LOS DATOS COMPRIMIDOS PUEDEN SER EXPANDIDOS EN UN MAPA DE BIT A ALTA VELOCIDAD. LOS DATOS DE IMAGEN QUE INCLUYEN DATOS EN COLOR SE COMPRIMEN EN LOS DATOS DE IMAGEN QUE TIENEN CAMPOS DE DIRECCION DE CODIGO A, CODIGO B Y CODIGO C QUE CONTIENEN LAS DIRECCIONES CORRESPONDIENTES A LOS DATOS DE IMAGEN EN LAS RAMS DE COLOR PARA ALMACENAR INFORMACION DE COLOR, CAMPOS DE CLASIFICACION PARA CONTENER INFORMACION DE CLASIFICACION ACERCA DE CATEGORIAS DE CLASIFICACION EN LAS CUALES LOS DATOS DE COLOR SE CONTIENEN CUANDO LAS RAMS DE COLOR SE CLASIFICAN EN CATEGORIAS PRESCRITAS A, B Y C, Y CAMPOS RL DE LONGITUD DE EJECUCION QUE CONTIENEN EL NUMERO DE DATOS DE COLOR CONTINUOS. PARA EXPANDIR DATOS DE IMAGEN COMPRIMIDOS, UN PRIMER PROCESO PARA DECODIFICAR CAMPOS DE CLASIFICACION, DETERMINA UNA CATEGORIA QUE CONTIENE DATOS DE COLOR, Y GENERA UNA DIRECCION MEDIANTE LA DECODIFICACION DE LOS CAMPOS DE DIRECCION BASADA EN LA CATEGORIA DETERMINADA Y UN SEGUNDO PROCESO PARA ACCEDER A LAS RAMS DE COLOR MEDIANTE EL SUMINISTRO REPETIDO DE LA DIRECCION GENERADA POR EL NUMERO DE CAMPOS DE LONGITUD DE EJECUCION CONTINUOS.
