Table 10 Impact of data augmentation on model performance
From: Skin lesion segmentation using deep learning algorithm with ant colony optimization
Augmentation Type | Description | Accuracy (%) | Dice coefficient (%) | Rate/Percentage Applied |
|---|---|---|---|---|
None | No augmentation applied | 92.1 | 88.9 | 0% |
Rotation | Random rotation of the image (0 to 360 degrees) | 94.8 | 92.3 | 25% |
Flip | Horizontal and vertical flipping | 94.5 | 91.7 | 50% |
Color Shift | Random change in color intensity | 93.9 | 91.0 | 20% |
Zoom | Random zoom-in or zoom-out of the image | 94.2 | 91.5 | 30% |
