Artificial Vision Using System No Blinds In The World

  1. 1. ARTIFICAL VISION USING EMBEDDED SYSTEM “NO BLINDS IN THE WORLD” Presented by R.PRABHU T.RAJKUMAR ||| YEAR ECE KGISL INSTITUTE OF TECHNOLOGY
  2. 2. INTRODUCTION: “We see with our brains than with our eyes”. The sole principle used to visionise a blind is –”DECEIVING OUR BRAINS”.
  3. 3. METHODS USED ARE a)Microchips. b)Nano tube implant. c)Digital artificial vision. d)Ocular prosthetics. e)Braile type writer
  4. 4. BRAILLE TYPE WRITER: ; • Using a signal processor synchronized signals are converted to pricking pulses, which is sensed on a bad interfaced on the stomach or hand of blind.
  5. 5. OCULAR PROSTHESIS (FALSE EYE) The BIONIC EYE implant are of porours polyethylene ,aluminum oxide .
  6. 6. DIGITAL ARTIFICAL VISION • MICRO COMPUTER a)Sub-notebook computer-Employs a 233 MHZ processor, 32 MB of RAM,4 GB hard disk, b)MICRO CONTROLLER-Consists of pulses 30 HZ to produce each frame
  7. 7. IMAGE PROCESSING • SOBEL filter is most common approach • They are Gx and Gy
  8. 8. MEMS • A new optical device, called the microelectromechanical systems– (MEMS- ) based adaptive optics phoropter (MAOP), will greatly improve this process. • The electrodes are embedded in silicone- based substrate polydimethylsiloxane (PDMS)
  9. 9. PROCESS IN A VISION FIELD OF BRAIN IN A HUMAN Video camera Analog signal NTSC link Digital signal Sub-notebook computerMicro controller Edge Detected image Electrical impulses Electrodes (phosphenes) Visual field edged image
  10. 10. The original image seen by the camera and phosphene image seen by the visual field in the brain of the blind human are as shown
  11. 11. HUMAN VISUAL SYSTEM
  12. 12. ELECTRODE IMPLANTATION:
  13. 13. NANOTUBES AND NANOBATTERIES: • Age related retinal diseases like macular dysfunction, retinitis pigmentosa can be averted using nano tubes.
  14. 14. FUTURE APPLICATIONS: • As now, only black and white images are seen by this AVS system, research is being carried to visualize coloured images by using optical fiber technology. • Research is being carried to replace the electrode implantation with ray or wave devices • NVCS can be nano fabricated on a single chip
  15. 15. CONCLUSION: • “WISHING A REMARKABLE PROGRESS IN THE DEVELOPMENT OF THIS ARTIFICIAL VISION SYSTEM, SUCH THAT EACH AND EVERY BLIND PERSON TODAY, IS NEVER A BLIND TOMMOROW.”
  16. 16. THANK YOU
