public class AlgorithmFuzzyMinimization
extends AlgorithmBase

This algorithm performs minimization of fuzziness, a reduction of the amount of fuzziness. This method is probably the first fuzzy approach to image enhancement and is also known in the literature as contrast intensification operator. The main idea is to reduce the amount of image fuzziness. The algorithm is as follows: 1.) Gray-level fuzzification (u(g) denotes the degree of brightness) u(g) = pow(1 + (gmax - g)/Fd, -Fe) where Fd and Fe are the exponential and denominational fuzzifiers that control the amount of grayness ambiguity in the membership plane. Suitable values for Fe are 1 and 2. Fd is computed from a user selected crossover gray scale value, gc, at which u(gc) = 0.5. gmax is the maximum gray level in the new image. gmax >= srcMax. alpha = pow(1 + (gmax - gmin)/Fd, -Fe) gmin
