Abstract

En este documento se presenta una metodología para el preprocesamiento de mamografías, el cual se divide en tres pasos: reducción del área de trabajo, reducción de ruido y realce de contraste. Los mejores resultados en la etapa de reducción de ruido se obtuvieron con la técnica que empleo la transformada wavelet (WT), para un ruido con una desviación estándar sigma=10 se obtuvo una relación pico señal a ruido (PSNR) de 32.69, valor aproximado al obtenido en 2 , en la etapa de realce de contraste los mejores resultados se obtuvieron con una combinación de técnicas de filtrado espacial y ecualización del histograma.
