Accurate optic disc and optic cup segmentation plays an important role for diagnosing glaucoma.
However, most existing segmentation approaches suffer from the following limitations.
On the one hand, image devices or illumination variations always lead to intensity inhomogeneity in the fundus image.
On the other hand, the spatial prior knowledge of optic disc and optic cup, e.g., the optic cup is always contained inside the optic disc region, is ignored.
Therefore, the effectiveness of segmentation approaches is greatly reduced.
Different from most previous approaches, we present a novel locally statistical active contour model with the structure prior (LSACM-SP) approach to jointly and robustly segment the optic disc and optic cup structures.
First, some preprocessing techniques are used to automatically extract initial contour of object.
Then, we introduce the locally statistical active contour model (LSACM) to optic disc and optic cup segmentation in the presence of intensity inhomogeneity.
Finally, taking the specific morphology of optic disc and optic cup into consideration, a novel structure prior is proposed to guide the model to generate accurate segmentation results.
Experimental results demonstrate the advantage and superiority of our approach on two publicly available databases, i.e., DRISHTI-GS and RIM-ONE r2, by comparing with some well-known algorithms.
