Conference paper


This paper describes an effective method for performing both image denoising and contrast/brightness enhancement to images corrupted with a wide category of noise. The method employs a Real-Coded Genetic Algorithm with subjective fitness and a novel crossover operator called Gaussian Uniform Crossover. The algorithm evolves the structure of a general Order Statistics Filter (OSF). Results are presented that indicate the efficiency of the method proposed as compared to classical filtering methods.
