| Abstract: | In this paper, a new image coding method based on wavelet transform-improved adaptive binary arithmetic coding, is proposed. The algorithm codes an image into multi-layer bitstream, and then the multi-layer bitstream is coded ulteriorly with the improved adaptive binary arithmetic. The comparison results show that the improved data conversion method is more effective than the embedded zerotree wavelets encoding algorithm. |
