| dc.description.abstract | A score function useful as a quantitative measure of the performance of the medical image enhancement techniques is reported in this paper. The measure proposed is based on merging of full–reference and blind–reference image enhancement measures. The score function is the average of the weighted sum of the image enhancement measures normalized between zero and one. The novel measure is validated considering as a hypothesis that values maximizing score function have that maximize the values of the metrics (Dice coefficient) used to evaluate certain previously reported cardiac image segmentation approach. The values of score function and Dice score reached the maximum value for the same cardiac volumes segmented. | eng |
| dc.description.abstract | En este artículo se presenta una función de puntuación útil como medida cuantitativa del rendimiento de técnicas de mejora de imágenes médicas. La métrica propuesta se basa en la fusión de medidas de mejora de imagen de referencia completa y referencia ciega. La función de puntuación es el promedio de la suma ponderada de las medidas de mejora de imagen normalizadas entre cero y uno. La nueva medida se valida considerando la hipótesis de que los valores que maximizan la función de puntuación tienen como máximo los valores de las métricas (coeficiente de Dice) utilizados para evaluar cierto enfoque de segmentación de imágenes cardíacas reportado previamente. Los valores de la función de puntuación y el coeficiente de Dice alcanzaron el valor máximo para los mismos volúmenes cardíacos segmentados. | spa |
