Abstract :
Based on zerotree method, hybrid self-adapting arithmetic encoder is used compared with Shapiro´s single base encoder. Rejecting significant coefficients´ sequence according to their amplitudes is adopted. Simulation result is given and reconstructed image effect based on improved scheme is perfect
