The Quaternionic Wavelet Transform is a recent improvement of standard wavelets that has promising theoretical properties. This new transform has proved its superiority over standard wavelets in texture analysis, so we propose here to apply it in a wavelet based image coding process. The main point is the interpretation and coding of the QWT phase, which is not dealt with in the literature. At equal bitrates, our algorithm performs better visual quality than standard wavelet based method.
