Keypoint annotation
With Keypoint annotation, points are placed on things like joints, eye corners or a parcel's corners, so a model can read shape and pose. Pricing is per point; a dozen or more points can make up one full body skeleton.
Estimate the cost of a keypoint annotation job
136,000 points overall, drawn as squares of 10,000 points
That makes 136,000 points across 8,000 images. What a team outside the US would charge, roughly:
$2,040 to $13,600
Teams abroad list between $0.015 and $0.10 for each point.

The published low and high price for that label type gets multiplied by the label count. Another review adds 20 to 50 percent, while a US team costs two to four times the outside-US range.
Prices for image tags come from Kili Technology for the low end and BasicAI for the high end.
Prices for bounding boxes come from Label Your Data for the low end and Habile Data for the high end.
Prices for polygons come from AnnotationBox for the low end and Habile Data for the high end.
Prices for keypoints come from Label Your Data for the low end and Habile Data for the high end.
Prices for pixel masks come from Habile Data for the low end and GDS Online for the high end.
Landmarks and skeletons
Points are joined by a skeleton in a set order, for example shoulder, elbow and wrist. Give the vendor your exact list and order before work begins, or points won't match from one image to the next.

Common questions about keypoint annotation
What does keypoint annotation cost?
Per point, published rates run from $0.015 to $0.10.
Who provides image labeling?
On their own sites, iMerit, Sama, CloudFactory, Shaip, Cogito Tech, Toloka and Innodata all list this work, as do Scale AI, Appen, TELUS Digital, Mindy Support, Label Your Data, Keymakr and Anolytics. The vendor table shows, row by row, where each company is based and how it prices the work.
Is it possible to try a vendor before I sign?
Yes. Label Your Data runs a free pilot, CloudFactory will analyze a sample set at no charge and Keymakr sends over a sample batch you can correct ahead of the full batches. Ask for a small paid trial job in the brief; that is normal with the others.
