Abstract

Un dispositivo para decodificar datos de nube de puntos codificados puede configurarse para: para un punto de una nube de puntos, determinar un primer valor de atributo para un primer componente de color basado en un primer valor previsto y un primer valor residual; aplicar un factor de escala al primer valor residual para determinar un segundo valor residual previsto, en donde el factor de escala tiene uno o ambos de un valor no entero o un valor absoluto mayor que uno; para el punto de la nube de puntos, recibir un segundo valor residual en los datos de la nube de puntos codificados; determinar un segundo valor residual final basado en el segundo valor residual previsto y el segundo valor residual recibido; y para el punto de la nube de puntos, determinar un segundo valor de atributo para un segundo componente de color basado en un segundo valor previsto y el segundo valor residual final.
