Using the density of pixels in a histogram that comprised the graphical representation of the myocardial fibrosis areas as well as the myocardial without fibrosis areas, a semi-automatic threshold technique, that was able to distinguish the densities of the areas visually defined as presenting or not myocardial fibrosis, was applied.
Al utilizar la densidad de los píxeles en un histograma que comprendía la representación gráfica de las áreas con fibrosis miocárdica y las áreas de miocardio sin fibrosis, se aplicó de manera semiautomática una técnica de umbral que distinguía las densidades de las áreas con o sin fibrosis miocárdica, definidas visualmente.
