OPTIC DISC DETECTION IN RETINAL IMAGES USING AN EVOLUTION STRATEGY (μ+λ)
.
Sumario:
In this paper we present an optic disc (OD) detection approach based on evolution strategy (ES). The approach has two main steps: coarse detection and contour edge refinement. Coarse detection estimates an approximate position using an ES in which each individual has a fitness function based on the amount of bright pixels and the number of vasculature structure edge pixels inside a circle. The contour edge refinement uses a geometric approach to circle deformation in order to adjust the circle’s edge to the OD edges. To do so, the pixel with the greatest intensity value variation along a normal line is considered. The proposed approach was evaluated using the STARED and DIAREDB public repositories to process images of normal patients and th... Ver más
