Industry
Autonomous vehicles
Self-driving systems learn from labeled road data: vehicles, pedestrians, signs and lanes, frame after frame.
Our computer vision teams handle bounding boxes, object detection and tracking, and segmentation for this work. The workspace above shows the idea in miniature.
- Object detection & trackingVehicles, pedestrians and signs followed across frames.
- Image segmentationPixel-level regions for roads, lanes and surroundings.
- Keypoint & landmark annotationPrecise reference points for complex shapes and poses.
