(e) The pseudo-colored intensity image overlaid with the automatically detected cell edge (solid white), the dividing line involving the outer layer plus the rest from the cell mask (dotted white), plus the boundaries of person FAs (strong black). The area of interest (ROI) consists of the detected FAs positioned within the cell periphery region among the dotted and strong white lines.
