A New Genetic Based Multilayered Fuzzy Image Filter for Removing Additive Identical Independent Distribution Impulse Noise from Medical Images

By A. Padma, Dr. R. Sukanesh and A. Santhana Vijayan


Abstract:- In this paper, we develop a multilayered genetic based fuzzy image filter, which consists of fuzzy number construction process, a fuzzy filtering process, a genetic learning process and an image knowledge base. The introduction of multilayered fuzzy systems substantially decreases the no of rules to be learnt. First, the fuzzy number construction process receives noise free image and sample images and then constructs an image knowledge base for the fuzzy filtering process. Second, the fuzzy filtering process contains a parallel fuzzy inference system, a fuzzy mean process, and a fuzzy decision process to perform the task of removing impulse noise. Finally, based on the genetic algorithm, the genetic learning process adjusts the parameters of image knowledge base. Based on the criteria of Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE) and Mean Absolute Error (MAE), Genetic based fuzzy image filter achieves a better performance
