Webwhere γ can be seen as a gain factor of the high frequencies. For γ = 1, the filter is the identity map, f lp + f hp = f lp +(f – f lp) = f, and the output image equals the input image.For γ > 1 the relative highpass content in the image is increased, resulting in higher contrast; for γ < 1 the relative highpass content is decreased and the image gets blurred.
