and b and c control the threshold and rate of enhancement, respectively. It can be easily shown that f(y) is continuous and monotonically increasing within the interval [ — 1, 1] (similar to histogram equalization). Furthermore, a derivative off(y) of any order exists and is continuous. Therefore, enhancement using f(y) will not introduce new discontinuities (artifacts) into the reconstructed image.
