3D Optic Disc Reconstruction Via a Global Fundus Stereo Algorithm


Bansal, M., Sizintsev, M., Eledath, J., Sawhney, H., Pearson, D. J., & Stone, R. A. (2013, 3-7 July). 3D optic disc reconstruction via a global fundus stereo algorithm. Paper presented at the International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC ’13), Osaka, Japan.


This paper presents a novel method to recover 3D structure of the optic disc in the retina from two uncalibrated fundus images. Retinal images are commonly uncalibrated when acquired clinically, creating rectification challenges as well as significant radiometric and blur differences within the stereo pair. By exploiting structural peculiarities of the retina, we modified the Graph Cuts computational stereo method (one of current state-of-the-art methods) to yield a highquality algorithm for fundus stereo reconstruction. Extensive qualitative and quantitative experimental evaluation (where OCT scans are used as 3D ground truth) on our and publicly available datasets shows the superiority of the proposed method in comparison to other alternatives.
