Coarse-to-fine image registration for sweep fingerprint sensors
Author(s): Yong-liang Zhang; Jie Yang; Hong-tao Wu

Paper Abstract

For reconstructing sweep fingerprint sequences, we propose a coarse-to-fine image registration scheme, which first uses the block-matching method as the preregistration and then adopts the curvature-based elastic registration as a fine estimation of nonlinear distortions between two consecutive frames. With respect to two existing state-of-the-art approaches, the new scheme becomes more robust against distortions and therefore the reconstruction accuracy is improved.
