Abstract
- This paper represents the significance of Neurons in the Neural network. How it is shows its
importance when any tissue or layers of retina damaged. Blindness is more feared by the public than any other
ailment. Artificial vision for the blind was once the stuff of artificial neural network in the field of computer
science. But now, a limited form of artificial vision is a reality .Now we are at the beginning of the end of
blindness with this type of technology. In an effort to illuminate the perpetually dark world of the blind, the
technology has to be emerged that is electronic-based strategies designed to bypass various defects or missing
links along the brain's image processing pathway and provide some form of artificial sight. There are two
methods for curing blindness that will provide or restore vision which is Artificial Silicon Retina and artificial
retina component chip for the visually impaired around the world
. INTRODUCTION
The curing of blindness is the most challenging
and important area. Artificial-vision researchers
take inspiration from another device, the
cochlear implant, which has successfully
restored hearing to thousands of deaf people. But
the human vision system is far more complicated
than that of hearing. The eye is one of the most
amazing organs in the body. Before we
understand how artificial vision is created, it's
important to know about the important role that
the retina plays in how we see. Following points
indicates the explanation of what happens when
we look at an object
I. HOW TO CREATE ARTIFICIAL
VISION
A blind person could be made to see light by
stimulating the nerve ganglia behind the retina
with an electrical current. This test proved that
the nerves behind the retina still functioned even
when the retina had degenerated. Based on this
information, scientists set out to create a device
that could translate images and electrical pulses
that could restore vision[2]. Today, such a device
is very close to be available to the millions of
people who have lost their vision to retinal
disease. In fact, there are at least two silicon
microchip devices that are being developed. The
WORKING OF ARTIFICIAL VISION
SYSTEM
The main parts of this system are miniature
video camera, a signal processor, and the brain
implants. The tiny pinhole camera, mounted on a
pair of eyeglasses, captures the scene in front of
the wearer and sends it to a small computer on
the patient's belt. The processor translates the
image into a series of signals that the brain can
understand, and then sends the information to the
brain implant that is placed in patient’s visual
cortex. And, if everything goes according to
plan, the brain will "see" the
image
CONCLUSION
The applied methods and technique will be
helpful for the blind person to gain the vision
artificially from the innovative ideas.
