Abstract

SE DESCRIBE UNA TECNICA PARA CODIFICAR COMPONENTES DE COLOR DE SEÑALES DE VIDEO. SEGUN UNA PUESTA EN PRACTICA, UN COMPONENTE DE COLOR (U.V) DE UNA SECUENCIA DE SEÑAL DE IMAGEN SE FILTRA (EN 12,22) EN UNA PLURALIDAD DE SEÑALES DE IMAGEN DE SUBBANDA. UNO O MAS PIXELS DE UNA PRIMERA SEÑAL DE IMAGEN DE SUBBANDA SE CODIFICAN (Q16-1; Q261) USANDO UNO O MAS BITS DE UNA PRIMERA CANTIDAD DE BITS. LA PRIMERA SEÑAL DE IMAGEN DE SUBBANDA REFLEJA UNA ESTRUCTURA DE IMAGEN DE UN COMPONENTE DE COLOR DE LA SECUENCIA DE SEÑAL DE IMAGEN. LA PRIMERA SUBBANDA INCLUYE FRECUENCIAS ESPACIALES Y TEMPORALES BAJAS DEL COMPONENTES DE COLOR. UNA SEGUNDA CANTIDAD DE BITS SE USAN PARA CODIFICAR UNO O MAS PIXELS DE UNA SEGUNDA SEÑAL DE IMAGEN DE SUBBANDA. ESTA SEGUNDA CANTIDAD DE BITS SE COMPONE DE UNO O MAS BITS DE UNA PRIMERA CANTIDAD NO USADA PARA CODIFICAR PIXELS DE LA PRIMERA SEÑAL DE IMAGEN DE SUBBANDA. UNO O MAS PIXELS DE LA SEGUNDA SEÑAL DE IMAGEN DE SUBBANDA SE CODIFICAN (Q16-8.1; Q26-8.1) USANDO UNA O MAS DE LASEGUNDA CANTIDAD DE BITS. LA SEGUNDA SEÑAL DE IMAGEN DE SUBBANDA REFLEJA INFORMACION DE MOVIMIENTO DEL OBJETO DE IMAGEN DEL COMPONENTE DE COLOR DE LA SECUENCIA DE SEÑAL DE IMAGEN. UNA TERCERA CANTIDAD DE BIS SE PROPORCIONA PARA USARLA PARA CODIFICAR UNO O MAS PIXEL DE UNA TERCERA SEÑAL DE IMAGEN DE SUBBANDA. LA TERCERA CANTIDAD DE BITS CONSTA DE UNO O MAS BITS NO USADOS EN CODIFICAR NI LAS PRIMERAS NI LAS SEGUNDAS SEÑALES DE IMAGEN DE SUBBANDA. UNO O MAS PIXELS DE LA TERCERA SEÑAL DE IMAGEN DE SUBBANDA ESTAN CODIFICADOS (Q16-2, Q16-3; Q26-2, Q26-3) CON UNA O MAS DE LAS TERCERAS CANTIDADES DE BITS. LA TERCERA SEÑAL DE IMAGEN DE SUBBANDA REFLEJA BORDES DE OBJETOS DE IMAGEN EN MOVIMIENTO, POR EJEMPLO BORDES HORIZONTALES Y VERTICALES. TAMBIEN SE DESCRIBE UN METODO CORRESPONDIENTE DE SINTETIZACION DE IMAGENES A COLOR.
