Identifying the boundary of the optic cup excavation is of critical importance in the assessment of glaucomatous risk. Currently, most approaches are focused on the use of pallor. We present an automatic method to determine the cup excavation boundary based on vessel kinking in non-stereo retinal fundus images. The method tracks vessels using a self-initialized evolving model which adapts during propagation...
In this work, we introduce an alternative measurement to evaluate quality of flow field. We then present an alternative filter called OA-filter (Occlusion-Aware filter) which uses this measurement. It is integrated inside the solver to push the performance of the model in terms of accuracy and sharpness. The experiments show that the estimation result has been significantly improved. The method yields...
The objective of our work is to reconstruct the dense structure of a static scene observed by a monocular camera system following a known trajectory. Our main contribution is representated by the proposition of a TV-L1 energy functional that estimates directly the unknown depth field given the camera motion, thus avoiding to estimate as an intermediate step an optical flow field with additional geometric...
