Abstract
Se proporcionan métodos de codificación y decodificación de datos de video. En un método de codificación, los datos de video fuente que comprenden una o más vistas fuente se codifican en un flujo de bits de video. Los datos de profundidad de al menos una de las vistas fuente se filtran no linealmente y se submuestrean antes de la codificación. Después de la decodificación, los datos de profundidad decodificados se expanden y se filtran no linealmente.
