摘要
依据傅里叶变换和傅里叶频谱的性质,提出一种检测两幅图像间旋转角度的新方法。通过傅里叶频谱确定图像的主方向进而求得图像之间的旋转角度。实验表明论文方法能够很好地检测图像间的旋转角度。该方法简单可行,适应性好,有待进一步研究。
Based on the nature of the Fourier transform and Fourier spectrum,a new method is proposed for detecting between the rotation angle between the two images. By determining the main direction of the image obtained by Fourier spectrum,the angle of rotation between images is detected. The experimental results show that this method can detect the rotation angle images. This method is simple,feasible and adaptable. It needs further research.
