I am working with imaging data and after some thersholding I end up with a BW matrix so I can identify ROIs using regionprops and get a range of parameters for the ROI. So far so good. Now, I would like to quantify the signal within a set distance around each identified ROI (say 5 pixel wide perimeter)
Is there a simple way to do this, or I need to write something from scratch?
Any input is highly appreciated.
