摘要: 针对几何及颜色空间上均存在相似变换的两彩色图像的配准问题,提出一种四元数域双谱切片表达式。该表达式是对复数双谱切片对应的时域形式进行四元数傅里叶变换得到的结果,具有平移不变性,可用于两彩色图像旋转和尺度缩放的求解。仿真结果表明,与复数双谱切片法相比,四元数双谱切片法的抗干扰性更好,误差基本只有前者的一半。

Abstract: To solve the color image registration problem where similarity transformations may exist between two images both in spatial and color spaces, a new bispectrum slices formulation suitable for hypercomplex domain was presented. The formulation could be derived by applying the hypercomplex Fourier transform to the time domain form of the complex bispectrum slices. The resulting hypercomplex bispectrum slices was translation invariant and could be used to solve rotation and scale changes between two color images. The simulation results show that compared with the method of complex bispectrum slices, the proposed method has better robustness against disturbances. Its error is generally only half that of the former method.

Key words: hypercomplex, bispectrum, Fourier transform, registration, similarity transformation
