Abstract

Una implementación particular detecta los artefactos de corte de escena en una corriente de bit sin reconstruir el video. Un artefacto de corte de escena normalmente se observa en el video decodificado (1) cuando una imagen de corte de escena en el video original es recibida parcialmente o (2) cuando una imagen se refiere a una imagen de corte de escena perdida en el video original. Detectar los artefactos de corte, las imágenes de corte de escena candidato son seleccionadas primero y la detección de artefacto de corte de escena es realizada entonces sobre las imágenes candidato. Cuando se determina que un bloque tiene un artefacto de corte de escena, se asigna un nivel de calidad más bajo al bloque.
