I have a serious problem here. By using imfindcircles(), we can find circles of specified radius range only. Buy my image has circles with multiple sizes big and small. How can i use this function to detect circles of different radii. I also have another problem. To find the approximate radius of circles in image, we use imdistline. But how to find the radius of circles in the image dynamically i.e in the run time. Is there any other way to do this?? Please help!! Thank You in advance.

Have you considered regionprops() to find Eccentricity (to determine if an object is a circle) and MajorAxes (for diameter) ?

What happens if you widen your radius range to encompass all possible radii?

IMFINDCIRCLES allows you to specify a radius range which can include the entire range of expected radii.
