摘要: 利用对过采样Gabor变换系数的去冗余化设计,得到一种改进的临界采样Gabor变换。在这种改进的临界采样Gabor变换方法中,综合函数与分析函数可以同时具有良好的时频局域性及正则性,而其计算量则与一般的临界采样Gabor变换相当。

Abstract: By removing redundance from oversampling Gabor transform, an improved critical sampling Gabor transform is presented where its synthesis and analysis function possess favorable local properties and regularity simultaneously, while computation complexity of Gabor coefficient as much as that of conventional critical sampling Gabor transform. -
