摘要 对变形分数傅立叶变换相关做了进一步的理论研究,对待识别目标在单一方向上发生尺度缩放的情况,分别用变形分数相关和常规相关做了比对的仿真实验.得出与常规相关器相比,变形分数相关器具有更好的识别尺度缩放目标的能力. The conception of Anamorphic fractional Fourier transform correlation (AFrFTC) is analysed further. The computer simulations were performed to compare the results of AFrFTC and conventional correlation. It shows that the AFrFTC possesses more powerful capability of recognition in the case of the object to be recognized zooming in the lateral direction.
