The velocity field is calculated using a model similar to optical flow that is based on the advection-diffusion equation. The model is evaluated using a set of synthetic airfoil flow visualization images generated by a combination of computational fluid dynamics and inverse advection-diffusion equation approaches. The calculated velocity fields are in a good agreement with the true velocity fields"},{"@xml:lang":"sl","#text":"V današnjem času obstajajo številne vizualizacijske metode, ki omogočajo izračun hitrostnih polj opazovanega toka tekočine, pri tem pa je njihova glavna prednost, da so brezdotične in zato ne vplivajo na tok. Najpogosteje se uporabljajo metode, ki delujejo na osnovi križne korelacije (npr. PIV), znane pa so tudi metode na osnovi optičnega toka. PIV metode so dokaj uveljavljene za meritve hitrostnih polj, vendar pa je njihova slabost kompleksnost in razmeroma visoka cena merilnega sistema. Metode na osnovi optičnega toka lahko po drugi strani delujejo na tokovih z manj zahtevno izvedbo vizualizacije (npr. dim, delci...), vendar so v primerjavi s korelacijskimi še dokaj neuveljavljene in slabo računalniško podprte"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-KA17ZK5T","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-KA17ZK5T"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-KA17ZK5T/ebd17456-622c-4b31-8fdb-e1fde6e60b2d/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-KA17ZK5T/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-KA17ZK5T"}}}}
