Abstract:
A new method for level slicing operation of optical images, utilizing the nonlinear characteristics of photographic film and the complementary properties of the positive-negative is described. The mathematical model of the characteristics curve is proposed, and the relation between the contrast of level slicing, the γ value and the exposure is discussed. The experimental results are presented. The advantage of this method is that it employs noncoherent source and is very simple.
