“…Note that a significant error of the calculating the current velocities using the MCC technique occurs for the cases of displacements of a slick band along itself, particularly if the band has no specific features (or has small-scale features compared to the size of the subimage). That is why the "manual" processing or the technique of the "tracking" of individual slick roughness displacements can be applied along with the software processing using the MCC method [12].…”
