If not, could you please send it to me? Thank you! Sample MATLAB code is available for Xie and Ji's Ellipse Detection is available in the Wikipedia article about Hough Transforms - see link. Unfortunately, though it is just code and there isn't any test data or unit tests to confirm its operation. My initial investigations indicate that there are some problems with this code. I'm attempting to detect ellipses in ultrasound images for an academic project, so I would be delighted if anyone could provide me with access to working code with tests for ellipse detection under any sort of open source, academic or non-commercial use licence. This would save me a few weeks getting the wikipedia code into some sort of useful state. I would be interested in hearing from anyone who wants to collaborate on providing MatLab ellipse detection functions written to professional standards with a view to making them freely available to academic researchers. http://en.wikipedia.org/wiki/Hough_transform 1.
