ADJCONTRAST- Adjusts image contrast using sigmoid function. function g = adjcontrast(im, gain, cutoff) Arguments: im - image to be processed. gain - controls the actual contrast A value of about 5 is neutral (little change). A value of 1 reduces contrast to about 20 of original A value of 10 increases contrast about 2.5x. a reasonable range of values to experiment with. cutoff- represents the (normalised) grey value about which contrast is increased or decreased. An initial value you might use is 0.5 (the midpoint of the greyscale) but different images may require different points of the greyscale to be enhanced.
