how to detect all local minima in radon transform and average distance between them?

I want to detect motion blur parameters in image using radon transform.
im= imread ('blurredimage.tif');
Rd=radon(log(abs(fft2(diff(im)))));
mx=max(Rd(:));
(Row column)=find(mx==Rd)
Here column gives blur angle theta i.e. blur direction.
I got stuck in computing blur length,
Blur length is computed by finding avg dist of local minima in radon transform.
