The application of fuzzy logic to JPEG

To achieve the efficiency and automatic control, a fuzzy controller to incorporate with the JPEG lossy model is proposed. The simulation results based on USC 15 pictures indicate that this JPEG model equipped with the designed fuzzy controller is insensitive to the given initial input values, that is, (with the help of fuzzy controller) this JPEG can always find the proper values of inputs for desired distortion ratio even though the relation of input parameters and the output distortion ratio is not known. In addition, the effect of different defuzzification techniques to accuracy and convergence speed is studied as well.<
