Biorthogonal wavelet theory and techniques for image coding
Qingyun Shi · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1998
This paper concentrates on two issues related to wavelet- based image coding. At first, an algebra method is proposed to select biorthogonal wavelets for higher compression ratio and better quality of the reconstructed image. Then, a general algorithm is given to convert a discrete biorthogonal wavelet transform into lifting steps, so that one version of the transform, which maps integers to integers, can support both the lossy and lossless coding to facilitate the region of interest based image compression.
