Abstract

Se presentan enfoques para la selección de la precisión del vector de movimiento ("MV") durante la codificación de video. Estos enfoques pueden facilitar la compresión que es efectiva en términos del desempeño de distorsión de tasa y/o de eficiencia computacional. Por ejemplo, un codificador de video determina la precisión MV para una unidad de video de entre múltiples precisiones MV, que incluyen una o más precisiones MV de muestra fraccionada y la precisión MV de muestra entera. El codificador de video puede identificar un grupo de valores MV que tienen la precisión MV de muestra fraccionada, después selecciona la precisión MV para la unidad con base por lo menos en parte en la prevalencia de los valores MV (dentro del grupo) que tiene una parte fraccionada de cero. De otra forma, el codificador de video puede llevar a cabo un análisis de distorsión de tasa, en donde el análisis de distorsión de tasa se impulsa hacia la precisión MV de muestra entera. De otra forma, el codificador de video puede recolectar información acerca del video y selecciona la precisión MV para la unidad con base por lo menos en parte en la información recolectada.
