An automated classification of Computerized tomography (CT) images method uses Coiflet wavelets to extract features as input for the classifiers. Support Vector Machine (SVM) module is used to classify the images into different classes. Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) are used to optimize the parameters C and gamma of the RBF(More)
