Abstract :
Multifilter banks that have all properties of arbitrary order vanishing moment, optimum time-frequency resolution, symmetry and orthogonality together are constructed for the first time. Thus overcome the shortcoming of the present orthogonal optimum time-frequency resolution multifilter banks that have only 2-order vanishing moment. Due to the excellent properties, application experiments in image compression showed that, our multifilter banks outperform the best tools known as multiwavelet SA4, CL and Jiang´s optimum time-frequency resolution J_EX2 in compressing with texture image.
