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.

Instance Segmentation of Dense and Overlapping Objects via Layering

1 code implementation7 Oct 2022 Long Chen, Yuli Wu, Dorit Merhof

Instance segmentation aims to delineate each individual object of interest in an image.

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.

Object Detection Based Handwriting Localization

no code implementations28 Jun 2021 Yuli Wu, Yucheng Hu, Suting Miao

We present an object detection based approach to localize handwritten regions from documents, which initially aims to enhance the anonymization during the data transmission.
