Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO DE CLASIFICACION DE LOS PIXELS DE UNA IMAGEN QUE PERTENECE A UNA SECUENCIA DE IMAGENES ANIMADAS ASI COMO A UN PROCESO DE INTERPOLACION TEMPORAL DE IMAGENES QUE UTILIZAN DICHA CLASIFICACION. EL PROCESO DE CLASIFICACION DE LOS PIXELS DE UN IMAGEN (T(J+1) OBTENIDA POR PROYECCION TEMPORAL DEL CAMPO DE MOVIMIENTO DE UNA IMAGEN T(J) PERTENECIENTE A UNA SECUENCIA DE IMAGENES ANIMADAS, ESTANDO DEFINIDOS LOS PIXELS DE LA IMAGEN T(J) POR UN VECTOR. MOVIMIENTO Y POR UNA ETIQUETA, PERTENECIENDO LA ETIQUETA A UNA CLASE "NORMAL, "OCLUYENTE" O "APARECIENTE", SE CARACTERIZA EN QUE: ANTES DE LA PROYECCION, TODOS LOS PIXELS DE T(J) ESTAN ETIQUETADOS COMO "APARECIENTES"; DESPUES, DURANTE LA PROYECCION TEMPORAL, EL ETIQUETADO SE MODIFICA EN FUNCION DEL ETIQUETADO DE LOS PIXELS DE T(J) DE MANERA A OBTENER UN ETIQUETADO SEGUN LAS TRES MISMAS CLASES. APLICACION EN EL TRATAMIENTO DE IMAGENES DE TELEVISION.
