Adaptive polyphase subband decomposition structures for image compression

Gerek, Ömer Nezih; Çetin, AE (IEEE-Inst Electrical Electronics Engineers Inc, 2000)

Subband decomposition techniques have been extensively used for data coding and analysis. In most filter banks, the goal is to obtain subsampled signals corresponding to different spectral regions of the original data. ...
Lossless image compression using an edge adapted lifting predictor

Gerek, Ömer Nezih; Çetin, AE (IEEE, 2005)

We present a novel and computationally simple prediction stage in a Daubechies 5/3 - like lifting structure for lossless image compression. In the 5/3 wavelet, the prediction filter predicts the value of an odd-indexed ...
