N2 - This paper proposes a fast estimation method of subpixel displacement of images using the phase-only correlation with chirp transform algorithm. The subpixel displacement estimation using phase-only correlarion has high robustness and accuracy but requires high computational cost. The chirp transform is used to the subpixel displacement estimation to reduce the computational cost when the range of displacement to be estimated is limited to small area. The proposed method is applied to the displacement estimation of images, and is able to reduce computation time to 1/3 of that of a conventional method.
