How to Improve Accuracy Of Finding Circularity Algorithms?

Hello...

I have architectural building project image with a tif file.The image has some quarter circles that representing the doors. I tried to implement imfindcircles and regionprops (with eccentricity) functions in Matlab. But unfortunately functions didn't give us a efficient solutions like some circles couldn't find and some circles find that there is no circle exist in that locations. Is there any different idea or solution? I also attached my image with jpg file.

Thanks...

I see multiple entries in MATLAB answers with this same subject line.

If these are all asking the same question then please delete the redundant entries.
