Table 3 Computerized quantification of retinal features (Regions = [PE_L, PA_L, Fovea, PA_R, PE_R])
From: Retinal status analysis method based on feature extraction and quantitative grading in OCT images
Ophthalmologists focus features | Computer quantitative features | Feature type |
|---|---|---|
Retinal thickness | Thickness feature (\(T_{Foveola}\),\(T_{Regions}\) ), | Geometric features |
Thickness ratio feature (\(TR_{Regions}\)) | ||
Boundary continuity | Standard deviation (\(\sigma _{ILM}\), \(\sigma _{RPE}\)), | Morphological features |
Correlation coefficient (\(r_{ILM}\), \(r_{RPE}\)) | ||
Boundary smoothness | Gradient (\(\nabla Y_{ILM}\), \(\nabla Y_{RPE}\)), | Morphological features |
Curvature (\(K_{ILM}\), \(K_{RPE}\)) |
