Las máscaras de convolución son útiles para extractar información relevante de una imagen. Este artículo presenta una técnica para la evaluación del efecto de estas máscaras a través de la transformada de Fourier, haciendo uso de su propiedad de convolución y su aplicación en la encriptación de imágenes.
