exponent and amplitude
As a final step in the filter a gamma correction is passed on each channel, this correction is of the form:
gamma = amplitude * pow(channel, exponent) + offset
This gamma correction enhances the overall contrast in the image. A higher exponent will make the dark areas darker, while a higher amplitude brightens the lighter areas.
The offset in this component will always be 0.
