Abstract

Se proporciona un método dinámico de codificación de imagen que utiliza una imagen codificada como imagen de referencia para predecir la imagen siguiente a codificar. El método incluye: un paso para aplicar un filtro a una imagen localmente decodificada de una imagen codificada de tal manera que se genere una imagen restaurada; un paso para establecer información de coeficiente de filtro en el filtro; un paso para codificar la información de coeficiente de filtro; un filtro para codificar la imagen localmente decodificada a utilizar como imagen de referencia o información específica que indica la imagen restaurada; y un paso para almacenar la imagen localmente decodificada o la imagen restaurada como imagen de referencia en una memoria de conformidad con la información específica.
