Abstract
Un método de procesamiento de video incluye determinar, para una conversión de un bloque de una imagen de video en un video y una representación de flujo de bits del video, gradientes de un subconjunto de muestras en una región para una operación de clasificación en un proceso de filtrado. La región tiene una dimensión de M×N y el bloque tiene una dimensión de K×L, en donde M, N, K, L son números enteros positivos. El bloque se encuentra dentro de la región. El método también incluye llevar a cabo la conversión con base en la determinación.
