Image annotation for AI

Image annotation is the process of creating metadata in the form of labels for image data. This type of annotation is used to create datasets for computer vision models so they can identify images and extract the information needed to make accurate predictions.

Image annotation plays an important role in computer vision, the area of artificial intelligence that trains computers to interpret and understand the visual world. By using annotated or labeled images to train machine learning models, machines can accurately identify and classify objects and then respond to what they "see".

Computer vision applications include:

Autonomous vehicles that can track their surrounding objects with cameras and sensors, and react depending on what is happening in the environment.
Real-time inventory tracking and customer journey solutions for retail stores to optimize merchandise placement.
Manufacturing solutions for automated product assembly, defect detection, safety compliance and more.

Our image annotation services include:


Bounding boxes

This is the most commonly used type of annotation for computer vision and involves using rectangular boxes to define target objects.


Image transcription

This task involves identifying and extracting text data from images to train computer vision solutions including Optical Character Recognition (OCR) systems.


Keypoint annotation

This type of annotation is used to label a single pixel in the image to indicate an object’s shape and to track variations in objects. It is often used for gesture and facial recognition.

Object detection

In this form of annotation, several objects are labeled in an image to make distinctions between different types of objects.

Image classification

With this image annotation method, the entire image is given a label so that a machine learning model can learn to recognize different characteristics of the same category of object.

Polygon annotation

This type of image annotation involves labeling images with irregular shapes and is the best way to ensure pixel-level precision.

Image captioning

Assigning a natural language description to images allows insights to be extracted that can help improve a variety of applications, from search results to captioning tools for video, and more.


Semantic segmentation

This image annotation method involves outlining the boundaries between similar objects. It is used for autonomous vehicles, medical image diagnostics, and more.

Image evaluation

Review and evaluate image quality for continuous improvement.
