Abstract

Se describe un método para procesamiento de medios visuales, el cual comprende: calcular, durante una conversión entre un bloque de video actual de datos de medios visuales y una representación de flujo de bits del bloque de video actual, un modelo lineal de componentes cruzados (CCLM) y/o un factor de escalamiento residual de croma (CRS) para el bloque de video actual basado, al menos en parte, en muestras colindantes de un bloque de luma correspondiente que cubre una muestra superior izquierda de un bloque de luma coubicado asociado con el bloque de video actual, en donde una o más características asociadas con el bloque de video actual se usan para identificar el bloque de luma correspondiente.
