Abstract

Técnicas de interpolacion de cuadros dentro de un esquema de codificacion de transformada unidireccional. La interpolacion de cuadros puede utilizarse para generar uno o más cuadros interpolados entre dos cuadros codificados sucesivos de baja frecuencia de acuerdo con un esquema de codificacion de transformada unidireccional. Tal interpolacion puede ser util para aumentar la velocidad de cuadro de una secuencia multimedia que es codificado vía transformadas unidireccionales. Además, las técnicas pueden utilizarse para interpolar cuadros extraviados, por ejemplo, que se pueden extraviar durante transmisiones inalámbricas.
