Investigation of methods of estimating geometrical misalignment in face images

Two methods of estimating the geometrical misalignment parameters for portrait images are considered in the work. The first method is based on use of the Fourier transform and application of the correlative approach and the second is based on calculating the moment characteristics of an image. Resul...

Description
Summary:Two methods of estimating the geometrical misalignment parameters for portrait images are considered in the work. The first method is based on use of the Fourier transform and application of the correlative approach and the second is based on calculating the moment characteristics of an image. Results of experimental studies are presented. The advantage of the method based on the Fourier transformation is shown. Recommendations for both methods are given.
