| 摘 要： | 利用Ｚａｋ变换和框架作为数学工具，本文给出了一种在整数倍过抽样时构造拟正交Ｇａ－ｂｏｒ展开的方法。由于拟正交Ｇａｂｏｒ展开的窗函数及对偶窗具有相同的形式，使得Ｇａｂｏｒ展开的计算特别简单。由于所构造的窗函数具有良好的时频局部特性，在计算机视觉和信号处理等领域有着广泛的应用前景

| Abstract: | A method of constructing orthogonal like Gabor expansion in the case of oversampling by an integer factor is presented. The method is based on frames and Zak transform. The expansion we constructed not only can be computed easily, but have good localization in time frequency space. It is hoped that it will find applications in such area as signal processing and computer vision. |
