摘要
基于Gabor变换和小波变换提出了变窗Gabor变换,讨论了它的若干优良特性。变窗Gabor变换包含了Fourier变换,Gabor变换,小波变换,因此是上述变换的一般化,基于上述变换对变窗Gabor变换提出了不同的快速算法。实际应用中可以根据不同的目的选择不同的窗函数,在不同的尺度和不同的频率上进行变窗Gabor变换。
In this paper, the varied windows Gabor transform based on Gabor transform and wavelet transform is suggested, and its good property is discussed. The varied windows Gabor transform includes scale transform, Fourier transform, Gabor transform and wavelet transform. The different fast algorithms of the varied windows Gabor transform are also studied. And the different window functions and the different parameters in according to different applications can be selected. Finally, some applications are given in image processing.
