- 25,000 high-resolution images (split into 18,000 for training, 2,000 for validation, 5,000 for testing; at an average resolution of ~9 megapixels) with pixel-wise annotations from >2 million manually drawn polygons
- 100 object categories, 60 of those instance-specific (i.e. to enumerate objects)
- Global geographic reach, covering North and South America, Europe, Africa, Asia, and Oceania
- High variability in weather conditions (sun, rain, snow, fog, haze) and capturing times (dawn, daylight, dusk, and even night)
- Broad range of camera sensors, varying focal length, image aspect ratios, and different types of camera noise
- Different capturing viewpoints (from road, sidewalks, and off-road)
