High-Quality Vector Field and Direct Vorticity Estimation Uusing the Affine Correlation Method
Original language description
We present a correlation method for direct vorticity computation of the fluid velocity field. The correlation method allows the affine transformation of a correlation window. It is shown that Lagrangian field of displacements is locally affine considering linear terms only. Using the Normalized-Cross-Correlation (NCC) combined with affine transformation and Newton-Raphson iterative method, six parameters defining this transformation are estimated. Subsequently, using these parameters, both displacementand vorticity can be computed, hence, these properties are being obtained for every single pixel directly during the correlation procedure.
