Advanced Electronic Materials, EarlyView.For achieving nonlinear preprocessing of visual information analogous to the retina and convolutional operations in the visual cortex at single device level, a three‐terminal 2D vdW ferroelectric heterojunction is proposed. The results shed light on integrating diverse bio‐inspired visual functions in optoelectronic neuromorphic devices for the benefit

Retinopathy of Prematurity Stage Diagnosis Using Object Segmentation and Convolutional Neural Networks [PDF]
arXiv, 2020 Retinopathy of Prematurity (ROP) is an eye disorder primarily affecting premature infants with lower weights. It causes proliferation of vessels in the retina and could result in vision loss and, eventually, retinal detachment, leading to blindness. While human experts can easily identify severe stages of ROP, the diagnosis of earlier stages, which are

Segmentation of Retinal Blood Vessels Using Deep Learning [PDF]
arXiv, 2023 The morphology of retinal blood vessels can indicate various diseases in the human body, and researchers have been working on automatic scanning and segmentation of retinal images to aid diagnosis. This project compares the performance of four neural network architectures in segmenting retinal images, using a combined dataset from different databases ...

Two‐Terminal MoS2‐Based Retinomorphic Devices with Enhanced Synaptic Plasticity
Advanced Electronic Materials, EarlyView.The two‐terminal retinormorphic devices are demonstrated on the functionalized substrate through plasma treatment. The functionalized substrate serves recombination centers, which can control the decay dynamics of excited carriers. These make modulating synaptic plasticity possible in two‐terminal retinormorphic devices.
