Abstract

En la presente se divulgan métodos y sistemas para codificar una imagen y decodificar un flujo de bits que puede representar una imagen codificada. Durante la codificación y decodificación, se aplican operaciones de cambio de escala para cambiar la escala de una entrada a un tamaño que se puede procesar por una capa de una red neuronal. Modalidades divulgadas en la presente proporcionan métodos para cambio de escala que logra un tamaño reducido del flujo de bits, mejorando así la compresión.
