【摘要】 多小波同时具有正交、紧支、对称等对信号处理十分重要的特性,并获得很好的应用。目前大多数的多小波需要相应的预滤波技术。本文提出一种对称/反对称正交滤波嚣构造的方法,然后通过平衡的方法构造相应的平暂滤波器。最后,以图像压缩实验来测试此种滤波器的性能,实验结果表明,不需任何预滤波,SAOBM的性能远远高于DGHM和CL多小波,接近或高于Bi9/7。更多还原

【Abstract】 Multwavelet has orthogonality, compacted support and symmetry, these properties are very important for signal processing. However, most of Multiwavelets require related prefilter. An approach to construction of symmetry/antisymmetry orthogonal filter is proposed and its related balanced filter is constructed, no any prefilter is required. Experimental results prove its performance is superior to DGHM and CL multiwavelets, closer to or higher than Bi9/7更多还原
