Abstract

Se presentan innovaciones en decisiones de lado de codificador que utilizan los resultados de coincidencia de bloque basada en hash. Por ejemplo, algunas de las innovaciones se refieren a formas para construir tablas hash que incluyen algunos (pero no todos) bloques uniformes. Otras innovaciones se refieren a formas para determinar la resolución de vector de movimiento basándose en resultados de coincidencia de bloque basada en hash. Otras innovaciones más se refieren a la detección de cambio de escena, que incluye selección de imagen de referencia a largo plazo y determinación de calidad de imagen durante la codificación.
