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.
