What is image annotation tool?

Manual image annotation is the process of manually defining regions in an image and creating a textual description of those regions. Computer Vision Annotation Tool (CVAT) is a free, open source, web-based annotation tool which helps to label video and images for computer vision algorithms.

What is image annotation in machine learning?

Image annotation is defined as the task of annotating an image with labels, typically involving human-powered work and in some cases, computer-assisted help. Labels are predetermined by a machine learning engineer and are chosen to give the computer vision model information about what is shown in the image.
