9 Data Annotation Tool Options for Your AI Project

Mar 10, 2022

Finding the right annotation tool is an important part of any computer vision project. A streamlined data annotation process leads to precise training datasets and high performance models.

However, the variety of options available for developers can sometimes be overwhelming. It can be hard to know which annotation tool fits best with your particular use case or application.

This blog will look at 9 of the most commonly used annotation tools and detail the features they offer and how much they cost. We hope this guide will help you find the right option for your project.

Keylabs

Keylabs is designed for accelerated annotation. To achieve this the image and video annotation tool offers a number of streamlining features:

  • Quick outlining function and augmented annotation
  • Interpolation algorithms to track objects across multiple frames in video annotation
  • Videos can be labelled by multiple annotators at the same time without affecting quality and objects tracking
  • Integrate every pre-annotation type, in line with the needs of your project.
  • Keylabs offers unique project management and workforce analytics capabilities. Keylabs workflow system links annotators and verifiers and distributes tasks between them efficiently
  • Each annotation operation is coupled with efficient keyboard hot keys
