08 May 2014 Detect circles with various radii in grayscale image via Hough Transform Detect circular shapes in a grayscale image. Resolve their center positions and radii. Author: Tao Peng Murthy, Pappu

I applied this to a micrograph containing circular fibers. The program recognized every single one of the fibers and marked its centers correctly. However, some of those fibers have zero radius which is obviously incorrect. Why?

I think matlab R2010b fails importing the image as an argument of your function, I used "imread" instead. Nice results, thanks.
