A field of experts model for optic cup and disc segmentation from retinal fundus images

We present a Field of Experts (FoE) model to segment the optic cup and disc from retinal fundus images. FoE learns a prior model of the cup and neuro-retinal rim region in the form of filters, without relying on hand crafted features. FoE filter responses are integrated into a Random forest (RF) classifier that outputs probability maps for the test image and finally segments the cup and rim. Experimental results show our method achieves significantly better performance than current state-of-the-art.
