Improved VGG Algorithm for Visual Prosthesis Image Recognition

IEEE Access
With the development of bio-informatics, visual prostheses have become an effective method for low vision people to restore visual function. To meet the visual needs of visual implant recipients, this study explored the problem of in vitro image ...

A 4+1 ARCHITECTURE FOR IN VIVO ELECTROPHYSIOLOGY VISUAL PROSTHESIS

Journal of Accessibility and Design for All, 2016
Researchers around the globe are working towards restoring vision to the blind through the development of a visual neuroprosthesis. Overcoming physical, technical and biological limitations represents one of the main challenges for the scientific ...

Electrode-free visual prosthesis/exoskeleton control using augmented reality glasses in a first proof-of-technical-concept study. [PDF]

Sci Rep, 2020
In the field of neuroprosthetics, the current state-of-the-art method involves controlling the prosthesis with electromyography (EMG) or electrooculography/electroencephalography (EOG/EEG).

Visual Prosthesis [PDF]

Perception, 2008
There are more than forty million blind individuals in the world whose plight would be greatly ameliorated by creating a visual prosthesis. We begin by outlining the basic operational characteristics of the visual system, as this knowledge is essential for producing a prosthetic device based on electrical stimulation through arrays of implanted ...

High-amplitude electrical stimulation can reduce elicited neuronal activity in visual prosthesis. [PDF]

Sci Rep, 2017
Retinal electrostimulation is promising a successful therapy to restore functional vision. However, a narrow stimulating current range exists between retinal neuron excitation and inhibition which may lead to misperformance of visual prostheses.
