Abstract:
The article discusses the problem of reconstructing the connectivity of reference lines on quasiperiodic images. In this case, the condition of maintaining the curve shape is fulfilled. Three methods are described: a modified line-drawing along the directional field and two options for solving the variational problem: the finite-difference method and the Euler-Lagrange equation.

Keywords:
directional field, reference line, quasiperiodic image, modified line-drawing, finite-difference method, Euler-Lagrange equation.
