SPECTRAL RADIUS OF BIORTHOGONAL WAVELETS WITH ITS APPLICATION
Qingyun Zou, Guoqiu Wang, Mengyun Yang · Journal of the Korean Mathematical Society · 2014
In this paper, a 2-circular matrix theory is developed, and a concept of spectral radius for biorthogonal wavelet is introduced. We propose a novel design method by minimizing the spectral radius and obtain a wavelet which has better performance than the famous 9-7 wavelet in terms of image compression coding.
