Abstract

Four types of algorithms are suggested in this paper to smooth images; three of them work in the special domain and the fourth works in the frequency domain. The first genetic algorithm uses smoothing filters which are called the median, mean or minimum as an objective function for the genetic algorithm each time. A style has been proposed to enhance the mean filter. The second genetic algorithm uses processes of morphology to perform smoothing operation, while the third and fourth ones utilize Gaussian filter as an objective function, but they differ in that the third genetic algorithm works in the special domain and the fourth in the frequency one.
