Generalized Hough Transform and OpenCv. I’m looking for an OpenCv implementation of Generalized Hough Transform, or at least something in c++.

The generalized Hough transform is used when the shape of the feature that we wish to isolate does not have a simple analytic equation describing its boundary. In this case, instead of using a parametric equation of the curve, we use a look-up table to define the relationship between the boundary positions and orientations and the Hough parameters.

The generalized Hough transform (GHT), introduced by Dana H. Ballard in 1981, is the modification of the Hough transform using the principle of template matching. The Hough transform was initially developed to detect analytically defined shapes (e.g., line, circle, ellipse etc.).

-The generalized Hough transform is essentially a method for object recognition.-Itisrobust to partial or slightly deformed shapes (i.e., robust to recognition under occlusion).-Itisrobust to the presence of additional structures in the image (i.e., other lines, curves, etc.).-Itistolerant to noise.

Does anyone have codes for the 'Generalized Hough transform'. Or knows a website that has some. I spent 2 days on Google trying to find some but, no forum and no tutorial that have found have code for the 'Generalized Hough transform'. They only have code for analytic curves (circles, ellipsis, parabolas,...

Generalized Hough transform. Itm is bool edge image of the template with edges marked ones Return the x,y location coordinates which gave the best match Also return the score of each this point (number of point matching) %The x,y are the coordinates in image Is in which the the top left edge of image Itm (1,1) should be positioned in order to give the best match.

Generalized Hough transform Two possible difficulties may occur in the above Hough transform method: (a) the shape has to be described by an equation, and (b) the number of parameters (dimensions of the parameter space) may be high.

From this question on stack overflow i know there is no opencv implementation for generalized hough tranform but in the opencv documentation here there is cv::GeneralizedHough class what does this class do? I know SIFT and SURF are good at object recognition but recognize small and specific shaped objects in image i think generalized hough tranform is good.
