Transformer-Based Multi-Prototype Approach for Diabetic Macular Edema Analysis in OCT Images

ICASSP 2023accepted

Optical Coherence Tomography (OCT) is the major diagnostic tool for the leading cause of blindness in developed countries: Diabetic Macular Edema (DME). Depending on the type of fluid accumulations, different treatments are needed. In particular, Cystoid Macular Edemas (CMEs) represent the most seve…

Multi-Modal Self-Supervised Pre-Training for Joint Optic Disc and Cup Segmentation in Eye Fundus Images

ICASSP 2020accepted

This paper presents a novel approach for the segmentation of the optic disc and cup in eye fundus images using deep learning. The accurate segmentation of these anatomical structures in the eye is important towards the early detection of glaucoma and, therefore, potentially avoiding severe vision lo…

A Wavefront Marching Method for Solving the Eikonal Equation on Cartesian Grids

ICCV 2015poster

This paper presents a new wavefront propagation method for dealing with the classic Eikonal equation. While classic Dijkstra-like graph-based techniques achieve the solution in O(M log M), they do not approximate the unique physically relevant solution very well. Fast Marching Methods (FMM) were cre…
