Retinal prostheses and artificial vision
WebFortunately, for most retinal prostheses, an external camera and a video processing unit are employed to be essential components, and allow image processing to improve visual perception for recipients. At present, there have been some studies that use a variety of sophisticated image processing algorithms to improve prosthetic vision perception. WebOct 27, 2024 · Perceptual fading following continuous stimulation affects prosthetic vision of both static and dynamic scenes by making them disappear completely or partially. However, we showed that perceptual fading of a static stimulus might be countered by head-scanning motions, which together with the persistence revealed the contours of the faded …
