Table 7 The grading decision-making of morphological features
From: Retinal status analysis method based on feature extraction and quantitative grading in OCT images
Grading conditions I \(Th3_{j}< Th2_{j}< Th1_{j}\) | Grading conditions II \(Th1_{j}<Th2_{j}< Th3_{j}\) | Grade | Deformation |
|---|---|---|---|
\(Th1_{j}\le M_{j}\) | \(M_{j}\le Th1_{j}\) | 3 | Serious |
\(Th2_{j}\le M_{j} < Th1_{j}\) | \(Th1_{j}<M_{j}\le Th2_{j}\) | 2 | Moderate |
\(Th3_{j}\le M_{j} < Th3_{j}\) | \(Th2_{j}<M_{j}\le Th3_{j}\) | 1 | Small |
\(M_{j}< Th3_{j}\) | \(Th3_{j} < M_{j}\) | 0 | Normal |
