| Abstract: | In this paper,we define the fractional quaternion Fourier transform based on reduced biquaternion algebra.The fractional quaternion Fourier transform can be seen as the generalization of reduced biquaternion Fourier transform.Moreover,the Parseval's theorem and convolution theorem associated with fractional quaternion Fourier transform was derived.Besides,the fast algorithms of fractional quaternion Fourier transform was given.In the end,the design of multiplicative filter was proposed in this paper. |
