The dataset includes 375 images. Lion are annotated in COCO format.
The following pre-processing was applied to each image:
- Auto-orientation of pixel data (with EXIF-orientation stripping)
- Resize to 640x640 (Stretch)
The following augmentation was applied to create 3 versions of each source image:
- Random rotation of between -18 and +18 degrees
- Random shear of between -10° to +10° horizontally and -10° to +10° vertically
- Salt and pepper noise was applied to 2.44 percent of pixels
