dc.description.abstractLa estimación de movimiento es comúnmente utilizada para reducir la redundancia temporal, en compresión de video, la cual tiene un alto costo computacional. La reducción de la redundancia temporal se realiza mediante la estimación de los cambios de posición de los objetos entre dos frames consecutivos para transmitir únicamente la información que ha cambiado. Los algoritmos comúnmente usados en la estimación de movimiento están basados en la comparación de bloques, llamado Block Matching. En este artículo se propone el uso de las diferencias entre frames para reducir el costo computacional de los algoritmos basados en Block Matching. La propuesta se basa en las diferencias entre frames, lo cual permite detectar movimiento. Esta información es usada como información a priori para decidir si se usa o no una estrategia de Block Matching para la estimación de movimiento. Se comprobó experimentalmente que el rendimiento de los algoritmos mejora considerablemente usando la detección de movimiento como información a priori, en tanto que la calidad de la reconstrucción se mantiene.spa

dc.description.abstractenglishMotion estimation is commonly used to reduce temporal redundancy in video compression, which has a high computational cost. The reduction of temporal redundancy is done by estimating the position changes of the objects between two consecutive frames to transmit only the information that has changed. The algorithms commonly used in motion estimation are based on the comparison of blocks, called Block Matching. This article proposes the use of the differences between frames to reduce the computational cost of algorithms based on Block Matching. The proposal is based on the differences between frames, which allows detecting movement. This information is used as a priori information to decide whether or not to use a Block Matching strategy for motion estimation. It was experimentally verified that the performance of the algorithms improves considerably using motion detection as prior information, while the quality of the reconstruction is maintained.eng
