Direction Selective Silicon Retina that Uses Null Inhibition

  title={Direction Selective Silicon Retina that Uses Null Inhibition},
  author={Ronald G. Benson and Tobi Delbr{\"u}ck},
Biological retinas extract spatial and temporal features in an attempt to reduce the complexity of performing visual tasks. We have built and tested a silicon retina which encodes several useful temporal features found in vertebrate retinas. The cells in our silicon retina are selective to direction, highly sensitive to positive contrast changes around an ambient light level, and tuned to a particular velocity. Inhibitory connections in the null direction perform the direction selectivity we… CONTINUE READING
