Abstract

Un método de codificación de datos tridimensionales codifica una pluralidad de puntos tridimensionales, e incluye: la selección de uno de dos o más modos de predicción para calcular el valor pronosticado de un elemento de información de atributo del primer punto tridimensional, de acuerdo con elementos de información de atributo de uno o más segundos puntos tridimensionales en las proximidades de un primer punto tridimensional (S3421a); calcular el valor pronosticado por el modo de predicción seleccionado (S3422a); calcular, como predicción residual, una diferencia entre un valor del elemento de información de atributo del primer punto tridimensional y el valor pronosticado calculado (S3423a); y generar una corriente de bits que incluya el único modo de predicción y la predicción residual (S3424a).
