Abstract
We propose an optical-digital method and describe an experiment on finger-prints identification. The identification is based on comparing feature-vectors of small dimensionality obtained via expanding directions fields for each finger-print in terms of the Hadamard basis. The employment of the operation of 'partial' images orthogonalization in the course of directions field calculation has made it possible to enhance the reliability of identification.
