The high-quality data you need

Computer vision annotation

Types of annotation

Bounding boxes

We provide bounding box annotation for 2D, 3D and video data. By using auto-labeling and smart interpolation, we can quickly scale to thousands of instances

Types of annotation


Polygons allow you to perform object detection with much more precision. With our trained workforce and tools for automated shape detection, we provide extreme accuracy

Types of annotation


Pose detection has never been easier! By using preset skeletons, we are able to annotate hundreds of facial and pose keypoints on each figure, both on images and videos

Types of annotation

Semantic segmentation

We provide both semantic segmentationand instance segmentation, which allow you to get the maximum amount of information out of your data

“We developed a great partnership with Humans in the loop, and their dedication to our projects is evident in the final results. The communication was convenient and fast, tools were easy to use, and we could monitor the progress of the project and report any issues at any time. We appreciate their attention to details and their creative approach that made our annotation pipeline more productive.”
