Algorithm 2. RNFL segmentation by firstly computing its region of interest.

1:
function RNFL( $g r a d I m g, B 1, p a r$ )
2:
$B W 1 = r m v R e g A b o v e L i n e (B 1, p a r . A b v W i d t h$ )
3:
$B W 0 = r m v R e g B e l o w L i n e (B 1, p a r . B l w W i d t h)$
4:
$B W = B W 0 ⨂ B W 1$
5:
$g r a d I m g = g e t G r a d i e n t M a p (i m g P a d, b r i g h t T o D a r k)$
6:
$R O I = g r a d I m g ⨂ B W$
7:
$[B 2, Y] = g e t S e g B o u n d a r y (R O I)$
8:
$r e t u r n [B 2, B W]$
9:
end function
