四元数小波变换是近年来对标准小波的一种改进,具有良好的理论性质。这种新的变换已经证明了它的优越性比标准小波在纹理分析,所以我们在这里提出将其应用在基于小波的图像编码过程。主要的一点是解释和编码的QWT阶段,这是没有处理的文献。在相同的比特率,我们的算法表现出更好的视觉质量比标准的基于小波的方法。
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.
