Is possible find arbitrary shape with Hough transform?
In imgproc.hpp are functions: HoughLines,HoughLinesP (probabilistic), HoughCircles, but I want find ellipses with narrowness, like digit 8. How can I modify sources of HoughCircles to find this?
Digit 8 may be considered as two circles. Show your shapes to clarify your case plz.
In http://i.imgur.com/ze0Pw2v.png are unregular, 8-like are 19,222,and 231, especially 19. Rest is not 8-like. How distinguish?
