Abstract :
A novel matching pursuit (MP) image coding method is presented. A block partitioning scheme is employed to effectively exploit the spatial characteristics of MP atoms. Experimental results show that the proposed method significantly outperforms the existing MP coding methods and thus bridges the gap in coding efficiency between MP- and wavelet-based approaches.
