Table 2 Quality gradation scale.
From: OIMHS: An Optical Coherence Tomography Image Dataset Based on Macular Hole Manual Segmentation
Quality perspectives | Low signal strength | Signal shield | Image blur |
|---|---|---|---|
Grading bits | 0/1-- | - 0/1 - | --0/1 |
Principle description | Signal strength ≤ 15 | Total or partial loss of retinal and choroid signal | Image has noticeable blur appeared in retina, MH, IRC, and choroid |
