Put threshold option in imregionalmax

Hi!

I have a 2D matrix A and I got with

   B=imregionalmax(A)

a binary array B. Here 1 is for a local maxima and zero else. Then I used

C = imdilate(B, ones(3)

to include also neighboring zeros into ones. Now I did not realized that imregionalmax finds any kind of maxima and I would like to put a threshold like the minPeakHeight option in findpeaks function. Is there any smart way to put a threshold f.ex. at 0.1*max(A)?
