Augmentations | Parameters | Probability |
|---|---|---|
Horizontal flip | – | 0.5 |
Shift scale rotate | Shift limit = 0.02 Scale limit = 0.2 Rotate limit = (−10,10) deg | 0.8 |
Random crop | Size = (224,224) | 0.8 |
Random brightness contrast | Brightness limit = 0.2 Contrast limit = 0.2 | 0.8 |
Multiplicative noise | Multiplier = (0.8, 1) Per channel = True | 0.8 |
