Abstract

Un método de mejorar una imagen de video eliminando los efectos de la vibración de la cámara que comprende las etapas de: obtener una trama de referencia; recibir una trama de entrada; determinar el vector de traslación de trama para la trama de entrada; trasladar la trama de entrada para generar una trama realineada; efectuar un filtrado de paso bajo en el dominio del espacio sobre los píxeles de la trama realineada; efectuar un filtrado de paso bajo en el dominio del espacio sobre los píxeles de la trama de referencia; determinar la diferencia absoluta entre los píxeles filtrados de la trama de referencia y los píxeles filtrado de la trama realineada; efectuar un filtrado de paso bajo en el dominio del tiempo sobre los píxeles de la trama realineada para generar la trama de salida si la diferencia absoluta es menor que un umbral predeterminado; y proporcionar la trama realineada como la trama de salida si la diferencia absoluta es mayor que el umbral predeterminado.
