Data Annotation Services

Image annotation services

With Image annotation services, your photos get tags, boxes, outlines, points or pixel masks so a vision model can spot and name their contents. Pick a label type to price your job, and send your brief to three vendors that handle image labeling.

What would your image annotation cost?

What do you need labeled?

Bounding boxes: a rectangle drawn around each object in a photo.

Who labels it?

50,000 boxes overall, drawn as squares of 1,000 boxes

That makes 50,000 boxes across 10,000 images. What a team outside the US would charge, roughly:

$1,000 to $6,000

Teams abroad list between $0.02 and $0.12 for each box.

The calculation behind this

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 bounding boxes come from Label Your Data for the low end and Habile Data for the high end.

What label type should you pick?

  • Tags: the cheapest choice, one or more words that describe the whole image.
  • Bounding boxes: for detection, a rectangle drawn around each object.
  • Polygons: for odd shapes like roofs or tools, an outline traced around them.
  • Keypoints: for pose and faces, dots placed on joints or landmarks.
  • Pixel masks: for scene understanding, with every pixel colored by class.

Common questions about image annotation services

What does image annotation cost?

For pixel masks, offshore rates run $0.20 to $3.00 per image; tagged images cost $0.01 to $0.10 each and boxes $0.02 to $0.12 each. A US-based team charges two to four times as much.

Is there a way to try a vendor before signing?

Yes. With most vendors a small pilot comes first; CloudFactory analyzes your sample files at no cost and Label Your Data offers a free pilot.

What is the cheapest label type?

Tags for the whole image, since one decision is needed per image. Because every pixel gets a class, pixel masks cost the most.

What companies provide image labeling?

On their own sites, this work is listed by Scale AI, Appen, TELUS Digital, Anolytics, Keymakr, Innodata, Toloka, Mindy Support, Cogito Tech, Shaip, Label Your Data, CloudFactory, Sama and iMerit. Every row in the vendor table shows a company's home country and how it sets the price.

Which of these vendors mention SOC 2 or ISO 27001?

On their own pages, 10 of the 14 mention a SOC 2 report and 11 mention ISO 27001. An outside audit, SOC 2, reviews how a company keeps client data safe; for running information security, the international standard is ISO 27001.
