Variational image segmentation for endoscopic human colonic aberrant crypt foci
Figueiredo, I. N.; Figueiredo, P. N.; Stadler, G.; Ghattas, O.; Araújo, A.The aim of this paper is to introduce a variational image segmentation method for assessing the aberrant crypt foci (ACF) in the human colon captured in vivo by endoscopy. ACF are thought to be precursors for colorectal cancer, and therefore their early detection may play an important clinical role. We enhance the active contours without edges model of Chan and Vese to account for the ACF’s particular structure...
