    Active contours technique for fringe evaluation of complicated fringe patterns
    (2010) Joishi, R.; Reddy, K.P.J.; Hegde, G.M.
    An improved technique based on active contours approach is presented for the analysis of non-uniform finite fringe interferograms. The technique is validated by demonstrating its application in analyzing the interferomertic image having non-uniform fringe pattern generated by a supersonic flow in front of a blunt body. A filtering method for identifying the flow parameters is presented as an extension of this technique. Proposed technique also provides an estimate of the heterodyning spatial frequency. © 2010 SPIE.
