Abstract

Un método de codificación de datos tridimensionales, en el cual: se hace una determinación sobre si usar o no una estructura de árbol octal para codificar una unidad especial en cuestión de entre una pluralidad de unidades espaciales incluidas en datos tridimensionales (S1522); si se determina que la unidad de espacio en cuestión se va a codificar al usar un estructura de árbol octal (SÍ en S1522), la unidad espacial en cuestión se codifica al usar una estructura de árbol octal (S1523); si se determina que la unidad espacial en cuestión no se va a codificar con una estructura de árbol octal (NO en S1522), la unidad espacial en cuestión se codificada al usar un método diferente a una estructura de árbol octal (S1524); e información que indica si la unidad espacial actual ha sido o no codificada con una estructura de árbol octal se agrega una corriente de bits (S1525).
