Definitions

  • Logic circuitry is provided to constrain acceptance or rejection of the leaves or objects by the system in response to a determination that at least one of the characteristics of brightness and two color tones exceeds a predetermined deviation from the preset standards.
  • One of the spectral bands is chosen to provide uniform reflectivity from the series of leaves or objects being sorted to normalize the size of the various objects to that of the background surface.
