哈特莱变换
Examples
- It is shown that , due to the real operations , the computation of the bi - orthogonal analysis window , the transforms coefficients , and the reconstruction of the original signal in rdgt case , can be significantly reduced as compared with the computation of those in the cdgt case . and the similarity between the rdgt and the discrete hartley transform ( dht ) allows the rdgt to utilize the fast dht algorithms for fast computation . meanwhile , the rdgt bears a simple relationship with the cdgt such that the cdgt coefficients can be directly computed from the rdgt coefficients
主要内容有：研究了一维和二维实值离散gabor变换( rdgt )方法，这种方法由于仅涉及实数运算，并可利用快速离散hartley变换算法加速变换，因而在计算双正交分析窗、变换系数以及信号重建方面都比复值离散gabor变换( cdgt )简单易于实现，并且rdgt系数与cdgt系数的实部和虚部有着非常简单的关系，因此前者的计算完全可以替代后者的计算，从而达到明显减小gabor变换计算量的目的。 - Though the two new methods can improve the effect of edge detection , they need the gabor and wavelet transforms which make the computation complex and cost much time and are not easy to used in real - time application . this paper presents an efficient fast approach to compute real discrete gabor coefficients by applying the fht ( fast hartley transform ) in gabor transform , also the fft ( fast fourier transform ) is proposed to used in compute the wavelet coefficients
虽然gabor和小波的引入能提高边缘检测的效果，但往往因其计算的复杂性而受到限制，本文提出了一种有效的离散gabor变换算法来计算有限离散实数信号的gabor系数，同时，也给出了基于fft的小波变换快速算法，为理论的快速实现提供了可能性。
