Enterprise Data Annotation & Computer Vision Services Hub

15+ annotation types across every major data format, delivered by an in-house team with built-in quality assurance.

What is Data Annotation Services?

Data annotation involves labelling raw data, such as images, video, text, or audio, to train machine learning models to identify patterns and make predictions. For example, the self-driving car model requires thousands of labelled images of pedestrians and road signs to safely recognize them in the real world.

AI/ML companies can now access the entire range of services and data annotation solutions from Annotation Support, from 3D LiDAR point cloud labelling, semantic segmentation, bounding boxes, video/audio processing, to custom data set curation, all of which can transform complex unstructured data into clean ground-truth training assets.

FAQ

Frequently Asked Questions

Find answers to the most commonly asked questions about our annotation services.

Data annotation is the process of labeling raw data — images, video, text, or audio — so machine learning models can recognize patterns and learn from it accurately. Without labeled data, AI systems can't be trained to identify objects, understand language, or make predictions. For example, training a self-driving car requires labeled images of pedestrians, road signs, and lane markings so the model learns to recognize them in real-world conditions.

Annotation Support offers 15+ annotation services, including bounding box annotation, semantic segmentation, polygon annotation, cuboid annotation, 3D LiDAR annotation, image masking, keypoint annotation, line annotation, and geospatial annotation, along with text, video, and audio annotation, instance segmentation, data labeling, image classification, image recognition, and image processing services.

Annotation Support provides annotation services across healthcare, agriculture, logistics, retail, finance, robotics, security and surveillance, sports, education, and university/research lab settings — covering use cases like autonomous vehicles, retail intelligence, image recognition, and robotics.

Annotation Support uses an in-house team (rather than outsourced freelancers) to handle every project, which helps maintain data security and consistent quality. The company has over 5 years of experience across 15+ annotation types and serves clients in the USA, UK, Australia, Japan, Germany, and other countries.

Annotation Support handles all major data types used in AI training, including images (bounding box, polygon, segmentation, masking), video, text, audio, and 3D point cloud data (LiDAR) — making it suitable for computer vision, NLP, and autonomous vehicle projects alike

Yes. Annotation Support executes all projects using its in-house team rather than third-party contractors, which is positioned as a key safeguard for data security and confidentiality throughout the annotation process.
