    Summary
    This summary is machine-generated.

    The MacLeod and Rosenfeld multiple-channel model accurately predicts visual system contrast sensitivity to various complex gratings. This model explains luminance gradient detection without special detectors and shows frequency-dependent phase sensitivity.
