2D Video Annotation Solutions

Sama delivers best-in-class video annotation services for the most complex and demanding machine learning models.

Detect and define the location of your target objects. Our video annotation experts use bounding boxes to accurately segment videos used for a variety of applications including autonomous driving, food system optimization, and more. Bounding boxes are best used for object tracking and object detection.

  • Achieve accurate placement with just two clicks with crosshair lines
  • Use state tracking for occlusion, truncation and overlapping objects
  • Create custom classes, multiple attributes per instance, and hierarchical relationships
  • Power up your object tracking with ML Assist for faster high-quality annotations
  • Use ML-assisted or linear interpolation between frames

Localize and detect complex objects with precision.

Polygons are used as part of our video annotation solutions to improve the accuracy of object detection algorithms. They are best used for applications when a more precise definition of an object’s boundaries are needed such as vehicle detection, crop identification and more.

  • Apply ML-assisted annotation for polygon for auto-annotation
  • Use grouping and layering for similar objects
  • Engage quick editing tools for adding and removing points
  • Create custom classes, multiple attributes per instance, and hierarchical relationships
  • Utilize linear interpolation between frames

Easily detect and annotate pose variations.

Keypoints are a video annotation technique that our team uses to capture the location and orientation of landmarks within a video. Keypoints are best for motion tracking, facial landmark detection and hand gesture recognition as they track the movement of individual objects.

  • Configure any custom keypoint shape including skeletons, hands, and eyes in a repeatable pattern for consistent results
  • Landmark important features using points
  • Get support for custom classes, multiple attributes per instance, and hierarchical relationships
  • Utilize linear interpolation between frames

Annotate straight or curved objects with precision.

Lines and arrows are used in 2D video annotation to highlight important features in a video for object tracking or scene understanding. This is useful for understanding things like lane marking and traffic patterns or identifying buildings in a city.

  • Outline object boundaries with lines for clear edge identification
  • Highlight directional indicators with arrows
  • Get support for custom classes, multiple attributes per instance, and hierarchical relationships
  • Utilize linear interpolation between frames
