Abstract :
A new method to recover (8×8) block losses for JPEG compressed images is proposed, which can be used in wireless UMTS and asynchronous transfer mode (ATM) networks. The problem of image reconstruction with (8×8) block losses is transformed to a system of linear equations using two-dimensional trigonometric polynomials. The simulation results show the feasibility of this method. The sensitivity analysis of the proposed method shows that this method is robust against additive noise
