摘要
A robust subpixel registration method for image mosaicing is presented in this paper. The method takes advantage of frequency-domain characterization to estimate the geometric transformation between images. The rotation and scale parameters between the to-be-mosaiced images are converted to translations by the Fourier-Mellin Transform (FMT), then the translation is estimated by the phase correlation method, finally the subpixel translation is refined through frequency upsampling. Images which can be mosaiced are stitched together after all the parameters have been estimated. The experimental results demonstrate the effectiveness and robustness of the scheme.
