Contrast Sensitivity Function

Categories: Pattern Recognition and Image Processing

Author(s): T.P. Pridmore, S.R. Pollard, S.T. Stenton

The contrast sensitivity function is a normalised description of a system's sensitivity to spatial frequencies in terms of the contrast required to perform some perceptual task. For detection tasks, the human C.S.F. peaks at around 3-5 cycles/deg and reaches zero at about 60 cycles/deg. See Modulation Transfer Function.
