Zerotree Wavelet Coding Using Fractal Prediction
Fractal image coding can be seen as spectral prediction of coefficients in the wavelet decomposition of an image. Fine scale coefficients are described by shifted and scaled coeff...

An automatic scheme for stereoscopic video object-based watermarking using qualified significant wavelet trees
In this paper a fully automatic system for embedding visually recognizable watermark patterns to video objects is proposed. The architecture consists of 3 main modules. During the...

Progressive fractal coding
Progressive coding is an important feature of compression schemes. Wavelet coders are well suited for this purpose because the wavelet coefficients can be naturally ordered accord...
