hend and confirm the system’s decision.
In the current study, blood vessel segments that
form a loop or overlap were not considered when cal-
culating the curvature index of the vessels. In addi-
tion, the present method is trained and evaluated with
a small number of retinal image datasets for three lev-
els of ROP-Plus disease classification. Therefore, in
the future, we may enhance the proposed techniques
to address overlapping problems with more retinal
image datasets and additional disease classification
levels.
