From: Retinal status analysis method based on feature extraction and quantitative grading in OCT images
Grading conditions | Grade | Deformation |
---|---|---|
\(G_{ref}* b_{3}\le G_{tar}\) | 3 | Serious |
\(G_{tar}\le G_{ref}* a_{3}\) | 3 | Serious |
\(G_{ref}* b_{2}\le G_{tar}< G_{ref}* b_{3}\) | 2 | Moderate |
\(G_{ref}* a_{3} < G_{tar}\le G_{ref}* a_{2}\) | 2 | Moderate |
\(G_{ref}* b_{1}\le G_{tar}< G_{ref}* b_{2}\) | 1 | Small |
\(G_{ref}* a_{2} < G_{tar}\le G_{ref}* a_{1}\) | 1 | Small |
\(G_{ref}* a_{1}< G_{tar}< G_{ref}* b_{1}\) | 0 | Normal |
