摘要
提出了一种在变换和重建时可采用不同决策算子的自适应算法,并将其应用到9/7小波的提升步骤中,组成了一个与JPEG2000相兼容、灵活的自适应提升系统.实验结果表明,此系统对奇异信号的处理优于9/7小波本身,具有很强的实用性和可推广性.
This paper proposes a novel adaptive lifting scheme adopting different decision maps for transformation and reconstruction. It is applied to the lifting steps of the 9/7 wavelet to form a flexible adaptive lifting system, which is compatible with JEPG2000. Simulation results show that it outperforms the 9/7 wavelet transformation and some other adaptive lifting schemes in the singular signal processing.
