Salem Said, Nicolas Le Bihan, Stephen J. Sangwine

AI总结:

提出一种离散复四元数傅里叶变换,通过四个标准复数傅里叶变换实现计算,并讨论其性质。

摘要:

引入了一种离散复四元数傅里叶变换。这是离散四元数傅里叶变换的推广,适用于信号/图像和变换核中任意一个或两者均为复四元数值的情形。展示了如何利用四个标准复数傅里叶变换来计算该变换,并简要讨论了其性质。

英文摘要:

A discrete complexified quaternion Fourier transform is introduced. This is a generalization of the discrete quaternion Fourier transform to the case where either or both of the signal/image and the transform kernel are complex quaternion-valued. It is shown how to compute the transform using four standard complex Fourier transforms and the properties of the transform are briefly discussed.
