Abstract

Se describen derivar parámetros de compensación de iluminación y detección de tipos de transiciones dominantes de iluminación para aplicaciones de procesamiento y codificación de video. Cambios de iluminación tales como fundidos de entrada, fundidos de salida, fundidos encadenados, y destellos se detectan. La detección de estos cambios de iluminación se utilizan entonces para predicción ponderada para proporcionar compensación de iluminación mejorada.
