Implant retinal learns to improve image

Software that can be taught to upgrade the quality of information sent from bionicheskogo eyes to the man being tested in Germany.

Implants retina may partially restore eyesight to some totally or partially blind people. They assume the work of transforming the light signals transmitted to the brain. So far, 10 people in Germany and 15 in the United States were vzhivleny such implants.

"These people can see the light or dark, and perhaps some vague form," said Rolf Ekmiller (Rolf Eckmiller), a scholar of computer science at the University of Bonn in Germany. "But they have no perception of a holistic way."

Ekmiller said that you can solve the problem by comparing the signals that create implants and signals that a healthy eye sends to the brain. One scientific team in California, USA, is trying to improve the software by constructing a copy of retinal neurons in silicon. Ekmiller with his colleagues Barusom Oliver (Oliver Baruth) and Rolf Shattenom (Rolf Schatten) plan instead to use learning software.

Ekmiller with his colleagues Barusom Oliver (Oliver Baruth) and Rolf Shattenom (Rolf Schatten) plan instead to use learning software. In their system, the camera transmits the information to "setchatochny coder" - software that simulates the processing of images performed healthy retina. "He had hundreds of different parameters that must be configured correctly," said Ekmiller. "But only one plant will correct the perception."

The team from Bonn University develops software which learns configured by the user. Tests, during which there were 50 computers of people who have been promising, said Ekmiller. Now scientists want to test the system on humans with these implants.
