You should look for the extreme values of the intensities. The dark regions of the image are not as dark as the circle, so find the lowest values and those will correspond to the black. Use some morphological operators and then you will be able to select only those of the "L".

What does "remove" mean to you? Do you want to crop the image? Do you want to fill it with white? Or black? Or smear in the pixels just outside of it with regionfill()?
