Nonlinearities of near-threshold contrast transduction

  title={Nonlinearities of near-threshold contrast transduction},
  author={Leonid L. Kontsevich and Christopher W. Tyler},
  journal={Vision Research},
The existence of analytic threshold nonlinearities was probed with 2AFC incremental threshold functions for both local and extended test patterns on stationary matched pedestals of the same and opposite sign. In contrast to the facilitation effect with same-sign pedestals, sensitivity with opposite-sign pedestals first deteriorated up to the mask detection level, abruptly improved and then deteriorated again. Analytic solutions for the transducer function with additive noise were derived to… CONTINUE READING
