Abstract

Se proporciona un método para detectar mejor un cambio de escena para proporcionar una predicción a un codificador a fin de permitir una codificación más eficiente, el método utiliza un Filtro Temporal de Movimiento Compensado (MCTF) que proporciona estimación de movimiento y está localizado previo a un codificador; el MCTF proporciona un Residual de Movimiento Compensado (MCR) utilizado para detectar la transición de cambio de escena; cuando una escena es relativamente estable, la clasificación MCR también es relativamente estable; sin embargo, cuando una transición de escena está en proceso., el comportamiento de la clasificación MCR cambia; algorítmicamente, la clasificación MCR es utilizada comparando la media deslizante de la clasificación MCR con la mediana deslizante; esta comparación resalta los puntos de transición; en el caso de un corte de escena, la clasificación MCR muestra un pico distinto; en el caso de una atenuación o disolución, la clasificación MCR muestra un periodo de transición de degradación seguido por la recuperación; al implementar la detección anterior utilizando el MCR, la ubicación de los I-cuadros en el proceso de codificación corriente abajo puede ser determinada con precisión con precisión para el codificador.
