Several alternative approaches to processing flow visualization images were recently introduced by the authors. Their common feature is processing a sequence of 2D images to detect presence and evaluate development dynamics of vortical structures, which are recognised as regions that differ from the uncorrelated turbulent background in the processed pictures by their high negative values of correlation coefficient.
