Abstract

Se proporciona eslamiento temporal y espacial de imagenes de video que incluyen planos de objetos de video (117, 118, 119, 405, 415, 420, 430, 520, 522, 524, 526, 532, 542, 705, 730, 750, 760, 780, 790, 805, 815, 820, 830, 850, 860, 880, 890) en una secuencia de video digital de entrada. Se mejora la eficiencia de codificacion mediante una compresion adaptable del video de modo de campo escalado. Los planos de objetos de video muestreados de manera ascendente (450, 490, 522, 542, 750, 790) en la capa de realce se reordenan para proporcionar una correlacion mayor con la secuencia de video de entrada basándose en un criterio lineal. El residuo resultante se codifica usando una transformacion espacial como la transformacion coseno discreta. Se usa un esquema de compensacion de movimiento para codificar los planos de objetos de video de la capa de realce (450, 460, 480, 490, 522, 524, 526, 542, 750, 760, 780, 790, 850, 860, 880, 890) escalando vectores de movimiento los caules ya han sido determinados para los planos de objetos de video de la capa de base (405, 415, 420, 430, 520, 532, 705, 730, 805, 815, 820, 830). Se proporciona un área de busqueda reducida cuyo centro está definido por los vectoes de movimiento escalados. El esquema de compensacion de movimiento es conveniente para su uso con video en modo cuadro o en modo campo. Varias configuraciones de procesador logran resultados de codificacion escalable particulares. Las aplicaciones de codificacion escalable incluyen video estereoscopico, imagen en imagen, canales de acceso de vista previa, y comunicaciones ATM.
