[Insight-users] Circule detection in itk

[Luis Ibanez]

Hi Ali,


1) How fast do you need the circle detection to be ?


2) How big are your images ?


3) Are you looking for full circles ?
    or only for circumferences ?


4) Do you expect to find multiple circles per image ?


5) Do you have any apriori information about the circle ?
    (eg. expected positions, expected radius, expected
     intensities)


6) Have you profiled the time that it takes to run the
    Hough circle detection in a release (optimized) build ?



   Please let us know,



      Thanks


        Luis
