利用滤波器,研究了在高密度离散小波变换下消失距的框架函数;由多带小波与多小波的设计启示,推导出小波的应用与算法的关系,并进一步研究在不同消失距个数作用下的紧框架.
We explore wavlets vanishing moments with framelets on higher-density discrete wavelets transform. By a few the filter banks, we do some research about wavelets and muhiband wavelets. It is a relation between scaling function and wavelets on different number of vanishing moments form a tight frame. Furthermore, it results to relate application and algorithm of wavelet methods.
