Lifting-based Wavelet Transform with Directionally Spatial Prediction

  title={Lifting-based Wavelet Transform with Directionally Spatial Prediction},
  author={Wenpeng Ding and Feng Wu and Shipeng Li},
This paper incorporates the directionally spatial prediction (DSP) into the conventional lifting-based wavelet transforms and proposes a novel, efficient and flexible lifting structure (referred as DSP-lifting hereafter). Each lifting stage can be performed at the direction, where pixels have a strong correlation, rather than always at the horizontal or vertical direction. The proposed DSP enables the predicting and updating process at the fractional pixel without any constraint on the… CONTINUE READING
