Abstract
método e sistema para compensação e transição de iluminação para codificação e processamento de vídeo. a presente invenção refere-se à derivação de parâmetros de compensação de iluminação e detecção de tipos de transições dominantes de iluminação para codificação de vídeo e processamento de aplicação. as alterações de iluminação como aparecimentos graduais, desaparecimentos graduais, esmaecimentos cruzados e flashes são detectadas. a detecção dessas alterações de iluminação é, então, usada para a previsão ponderada a fim de fornecer compensação de iluminação aprimorada.
