一种基于快速傅里叶变换的分区域图像配准方法
An Image Registration Method Based on Subregional Fast Fourier Transformation
摘要
Abstract
In order to improve the speed and precision of image registration, a method of image registration based on subre-gional fast Fourier transformation was proposed. A small area was selected in the image instead of the whole area, and then the ratio between the images and the rotation change was got based on the property of log-polar coordinate transformation and Fourier transformation, and the phase correlation technique (energy spectra) was used to determine the image transla-tion. Using those registration parameters, the global registration can be done. The method can improve the processing speed because of using a small area instead the whole image.关键词
