Optimizing Retinal Prosthetic Stimuli with Conditional Invertible Neural Networks

no code implementations7 Mar 2024 Yuli Wu, Julian Wittmann, Peter Walter, Johannes Stegmaier

However, the information transmission between the camera and retinal cells is often limited by the low resolution of the electrode array and the lack of specificity for different ganglion cell types, resulting in suboptimal stimulations.

A Deep Learning-based in silico Framework for Optimization on Retinal Prosthetic Stimulation

no code implementations7 Feb 2023 Yuli Wu, Ivan Karetic, Johannes Stegmaier, Peter Walter, Dorit Merhof

The pre-trained retinal implant model is also a U-Net, which is trained to mimic the biomimetic perceptual model implemented in pulse2percept.

Multiscale Softmax Cross Entropy for Fovea Localization on Color Fundus Photography

no code implementations8 Dec 2021 Yuli Wu, Peter Walter, Dorit Merhof

Fovea localization is one of the most popular tasks in ophthalmic medical image analysis, where the coordinates of the center point of the macula lutea, i. e. fovea centralis, should be calculated based on color fundus images.
