More Information
Summary:A swipe sensor image alignment method using the Fourier phase analysis and a system thereof are provided to arrange partial images which are generated by a bionic recognition sensing device using the swipe scheme. The first slice(502) and the second slice(504) are converted to a frequency domain. The shift data between the first and second slices is determined from only the phase components(506) of the converted first and second slices. In order to planarize an associated edge, the third slice and the fourth slice are windowed. The windowing is performed by using at least one of a tukey window and a hamming window. The areas of the third and fourth slices are expanded so as to obtain the first and second slices.
