Abstract

A novel extension of phase correlation to subspace correlation is proposed, in which 2-D translation is decomposed into two I-D motions thus only 1-D Fourier transform is used to estimate the corresponding motion. In each subspace, the first two highest peaks from I-D correlation are linearly interpolated for subpixel accuracy. Experimental results have shown both the robustness and accuracy of our method.
