15 Sep 2009 Hough Transform for circle detection An optimized Hough transform for circle detection. Author: Peter Bone LOVE

can some1 send me matlab program to find circle co-ordinate and radius in an image..
my email is <jain.deep108@gmail.com>

thanks , program works nice.

to run the program follow this code
houghcircle(i,10,4); % i=binary image containing a circle
                    % 10= radius, 4= threshold (>=4).
if u don t specify threshold it will be selected automatically.

everything is given nicely.

Can someone fill me in as to how this code works. Also, can it be altered to make an annulus as opposed to just a circle?

Could anyone plz tell me how to run the program..? when I run the program, it says "??? Error using ==> run at 56
Input argument "thresh" is undefined."

And sometimes.."??? Error using ==> run at 56
Input argument "Imbinary" is undefined."

Thanks.

 I apply this to a 512*512 logical image but get no results.
The function has an 'r' parameter, which is given by the author as follows:
"r - radius of circles."

I suspect the radius has to be specidifed precisely. If that is the case and the lagorithm requires a priori knowledge of the circle radius, I do not see much functionality in this.
