Abstract :
In this work, the performance of the MOI (mean-of-inversion) method with respect to accuracy and convergence speed is compared with that of the COA (center-of-area) method in the application of image library indices in which only very rough images are needed and high compression ratios are obtained. The simulation results based on 15 USC pictures indicate that MOI performs better than COA on convergence speed as target points located in the steep slope region of curves
