众所周知,在实际应用中用小波处理信号时,小波的对称性能使信号避免失真,小波的紧支撑性使得快速小波变换的和是有限和,小波的正交性能够保持能量等等,因而构造性质优良的小波就成为小波分析研究者关注的热点之一.近年来,插值型小波因具有易于初始化等独特的性质而被广泛地应用于数值计算,图象处理,积分方程数值解等领域,
In this paper, we construct bivariate three band interpolating scaling function. The constructed functions have excellent properties such as continuity, symmetry, interpolation. Furthermore, we study the sufficient and necessary con- ditions of bivariate three band compactly supported scaling function being interpolating and bivariate three band compactly supported real scaling function being symmetric and interpolating. These results can be easily applied to N-dimensional three band scaling function. Finally, we give an examole.
