Abstract :
In this work, the performance comparison of fuzzy controllers using the MOI (mean-of-inversion) defuzzification method and conventional proportional controllers with respect to accuracy and convergence speed in the application of image compression (JPEG) is given. The simulation results based on 15 USC pictures and various test points indicate that the performance of the fuzzy controller with MOI is less sensitive to its configurations than that of conventional proportional controllers. In additional, the largest performance difference between these two kinds of controllers is in the steep slope area
