Abstract | The present disclosure provides a method for decoding video data. The method comprises: obtaining a video block from a bitstream; determining a region to derive a multiple linear regression (MLR) model; obtaining luma and chroma sample values in the region; deriving the MLR model using the luma and chroma sample values in the region; predicting each of chroma samples in the video block by applying the MLR model to corresponding luma samples for that chroma sample; and obtaining decoded video block using the predicted chroma samples.
La presente descripción proporciona un método para decodificar datos de video; el método comprende; obtener un bloque de video a partir de un flujo de bits; determinar una región para derivar un modelo de regresión lineal múltiple (MLR); obtener valores de muestra de luma y croma en la región; derivar el modelo MLR utilizando los valores de muestra de luma y croma en la región; predecir cada una de las muestras de croma en el bloque de video aplicando el modelo MLR a las muestras de luma correspondientes para esa muestra de croma; y obtener un bloque de video decodificado utilizando las muestras de croma predichas. |
