abstract (eng):

The paper deals with features of a 2-D point set which are invariantwith respect to projective transform. First, five-point projective and permutation invariants are derived. Then, the invariants for more than five points are derived. The algorithm for searching the correspondencebetween the points of two 2-D point sets is presented. The algorithm is based on the comparison of two projective and permutation invariants of five-tuples of the points.
