Simulating prosthetic vision: II. Measuring functional capacity
Investigators of microelectronic visual prosthesis devices have found that some aspects of vision can be restored in the form of spots of light in the visual field, so-called "phosphenes", from which more rich and complex scenes may be composed. However, questions still surround the capabilities of how such a form of vision can allow its recipients to "see" and to carry out everyday activities....
متن کاملSimulating prosthetic vision: I. Visual models of phosphenes
With increasing research advances and clinical trials of visual prostheses, there is significant demand to better understand the perceptual and psychophysical aspects of prosthetic vision. In prosthetic vision a visual scene is composed of relatively large, isolated, spots of light so-called "phosphenes", very much like a magnified pictorial print. The utility of prosthetic vision has been stud...
متن کاملRetinal prosthetic strategy with the capacity to restore normal vision.
Retinal prosthetics offer hope for patients with retinal degenerative diseases. There are 20-25 million people worldwide who are blind or facing blindness due to these diseases, and they have few treatment options. Drug therapies are able to help a small fraction of the population, but for the vast majority, their best hope is through prosthetic devices [reviewed in Chader et al. (2009) Prog Br...
متن کاملSimulating prosthetic vision: Optimizing the information content of a limited visual display.
Visual prostheses for the restoration of functional vision are currently under development. To guide prosthesis research and allow for an accurate prognosis of functional gain, simulating the experience of a retinal prosthesis in healthy individuals is desirable. Current simulation paradigms lack crucial aspects of the prosthetic experience such as realistic head- and eye-position-dependent ima...
متن کاملThe Effect of Image Processing on Familiar Face Recognition with Simulating Prosthetic Vision
Many research teams have studied to make the blind see by stimulating the retina cells using electrical devices. But due to the limited number of electrodes, it needs to complement low resolution with image processing. In this paper, we tried to find the effect of image processing, especially with contrast enhancement (CE) technique. We investigated face recognition performance with three diffe...
