I am trying to calculate average RGB of images with a uniform background. So I want to remove the background from the calculation. How do I select only elements belows above/below certain value (say <250) and calculate average of those only.

Let A be your matrix......say you want values below a threshold val.
idx = A<val ;
themean = mean(A(idx)) ;
