Unsupervised image compression using graphcut texture synthesis
Stephen Ierodiaconou, James Byrne, David Bull, D.W. Redmill, Paul Hill · 2009
An unsupervised image compression-by-synthesis system is proposed utilising wavelet based image segmentation and analysis combined with patch based texture synthesis. High perceptual quality is ensured using an artefact detection algorithm in the encoder loop. EBCOT is used to transform code texture samples and residual image data. Resulting bitrate savings of up to approximately 17% over JPEG2000 for little change in perceptual quality have been shown.
