Resumen
El cáncer de mama constituye uno de los principales problemas de salud en la población femenina, por lo que la detección temprana resulta fundamental para mejorar el pronóstico clínico y aumentar las posibilidades de supervivencia. En este trabajo se presenta un método computacional para la clasificación automática de imágenes termográficas mamarias mediante técnicas de procesamiento digital de imágenes y aprendizaje profundo. El procedimiento propuesto emplea un proceso de segmentación basado en niveles de temperatura para identificar regiones térmicas de interés, las cuales son utilizadas como entrada de cinco modelos de redes neuronales convolucionales profundas. La evaluación experimental se realizó utilizando una base de datos compuesta por 1027 imágenes termográficas, correspondientes a 645 pacientes con cáncer de mama y 382 pacientes sin la enfermedad. Los resultados obtenidos muestran que el modelo VGG19 alcanzó el mejor desempeño de clasificación, con una sensibilidad del 100 %, una precisión del 100 % y una exactitud del 99.09 % utilizando un esquema de validación cruzada de dos particiones. Estos hallazgos demuestran el potencial del enfoque propuesto como herramienta de apoyo para la detección temprana del cáncer de mama y evidencian la efectividad del aprendizaje por transferencia en el análisis de imágenes médicas.
