| Abstract [eng] |
This paper discusses specific properties of the discrete orthogonal wavelet transform, namely: relationships between the wavelet coefficients and image fragments, existence of zerotrees in the discrete wavelet spectrum of an image, etc. In parallels, the progressive image encoding idea and an efficient image encoding/decoding algorithm EZW (Embedded-Zerotree-Wavelet), based on the discrete wavelet (Haar, Daubechies) transform, are presented. Some preliminary experimental analysis results are discussed. |
