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. 000003985 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000003985 653__ $$a 000003985 7112_ $$aEngineering Mechanics 2009$$cSvratka (CZ)$$d2009-05-11 / 2009-05-14$$gEM2009 000003985 720__ $$aTesař, V.$$iŠonský, J.$$iNěnička, V. 000003985 8560_ $$ffischerc@itam.cas.cz 000003985 8564_ $$s4179580$$uhttps://invenio.itam.cas.cz/record/3985/files/Tesar-104-PT.pdf$$y Original version of the author's contribution as presented on CD, 104. 000003985 962__ $$r3852 000003985 980__ $$aPAPER
