Artificial retina device and its manufacture

  title={Artificial retina device and its manufacture},
  author={T. Hashimoto and 武 橋本},
PURPOSE:To detect simply and at a high speed a bright/dark boundary in an image required for recognizing an object in an image and extracting its feature quantity, by optical filtering. CONSTITUTION:This device is provided with a Fourier-transformation lens 6 having a roughly planar emission surface, and for forming a Fourier- transformation image of information inputted from the incident surface 5 onto the emission surface, a filter 7 which is provided so as to adhere closely to the emission… Expand
