top-author share 44% 6 mo

bus factor = how many people it takes to cover more than half the commits (6 months). 1 is a solo project; higher means the work is spread across a team. top-author share is the single busiest author's slice of those commits.

why it's a big deal

  • An agent that has left the text box still needs hands for pixels, and supervision is the most-reached-for set of them - plug in any detector or segmenter and get back a clean, uniform set of detections.
  • It is quietly retrofitting for the agent era: the repo now ships AGENTS.md and CLAUDE.md, so a coding agent can learn how to use the library the same way a human would.
  • It turns one-off vision scripts into composable primitives - zones, trackers, annotators, dataset converters - which is exactly the shape an agent needs to assemble a pipeline without reinventing the plumbing.

under the hood

  • A model-agnostic detections API with connectors for Ultralytics, Transformers, MMDetection, Inference, and RF-DETR, plus highly customizable annotators for boxes, masks, and labels.
  • Trackers, line and zone counters, and dwell-time and speed-estimation utilities, alongside dataset tools to load, split, merge, and save COCO, YOLO, and Pascal VOC.
  • The 0.28 release adds CompactMask and SAM3 support, keeping the toolkit current with the latest segmentation models.
