Desarrollo de filtros digitales no lineales basados en modelos multirresolución

Abstract

En esta tesis doctoral se proponen y defienden nuevos algoritmos de filtrado no lineal, destinados a la eliminación de ruido impulsivo presente en la imagen, mejorando siempre las capacidades del filtro de mediana y similares. estos métodos de procesamiento se fundamentan en lo que se denomina en la presente tesis como mascara de eliminación de ruido. Se trata de una imagen binaria que localiza los pixeles afectados por el ruido, de manera que se filtran solo aquellas partes de la imagen que realmente lo necesitan. Tanto la mascara como el filtro en si operan utilizando la información proporcionada por las matrilces de composición, las cuales indican la probabilidad de que un pixel de una cierta región de la imagen tenga un determinado nivel de gris. Para comprobar la eficacia de los métodos propuestos se han realizado experiencias, comparando los resultados entre si, y con otros algoritmos de especial relevancia, ampliamente aceptados en la literatura
