Reviewing the Top 9 Image Annotation Tools in 2022

Sep 8, 2022

Finding the proper tools for computer vision, data labeling, and classification is a lifesaver. If annotating data feels like a laborious effort, there is a better method. You can expedite data annotations with the correct labeling tools and receive rapid, accurate results.

These tools are plentiful. But having many alternatives might make you feel like you're looking for a needle in a haystack. Luckily, there is a more practical option. Discover how to choose video and picture annotation tools.

Which image annotation tool should you choose

Every application can make data annotation jobs easier.

  • Data annotation toolkits consist of annotating, a database, and an interface.
  • AIA (automated image analysis) - These are perfect for many simultaneous annotations.
  • Image Annotation Using Computer Vision (CV) - Create a bespoke computer vision program using existing datasets, image analysis methods, and machine learning technologies.
  • Deep Learning (DL) Annotation Tools - Create deep learning frameworks without expertise. First, choose one that can support your data annotation activities. If you have copious quantities of data, consider a tool with batch processing and features like image cropping or resizing to optimize your workflow speed.

Consider the project's flexibility requirements, such as customization options, unique shortcut keys, or filters for particular items in images (like faces or cars). Consider manual picture annotation as well.

The top nine image and video annotation programs evaluated

This article discusses nine annotation systems for computer vision tasks. Your industry, purpose, and data types will determine your best option. Depending on the aims, some skills may be more significant. Choose the best image annotation tool to improve processes from the list below.

Keylabs Demo
  1. Keylabs

  2. Keylabs is a sophisticated video and image annotation tool that allows you to create unique datasets. You can leverage the company’s team to train your computer vision models using Keymakr data labeling services. Or, you can prepare the datasets yourself. The platform allows you to work with massive volumes of video or picture data without sacrificing speed or quality. Upload your image or video, add metadata, and then choose one of the tools, whether it's cuboids, bounding boxes, polygon, lines, points or other needed annotation type, to produce high-quality annotations.

  3. SuperAnnotate

  4. SuperAnnotate has extensive annotation features that allow you to perform annotations rapidly and with few clicks. Image annotating, image annotation software for semantic segmentation with adjacent pixels, keypoint tags, video tracking, and other features are in the tool. If you can afford it, it's perfect for speeding up computer vision tasks.

  5. Img Lab

  6. You may train object detectors here, allowing for greater customization. The annotate picture tool is plugin-based and supports a variety of label kinds. Use it without logging in, online or offline.


  8. The web-based solution combines several open-source features into a single powerful ML-based application. This cloud-friendly picture annotation tool is quick. It has all of the standard drawing tools and 3D point capabilities. An intelligent labeling system, in addition to specific labeling tools, may learn patterns through training.

  9. V7

  10. You can add characters, figures, and lines using the tools. V7 is an excellent choice for medical picture annotation software. You can email a link to it or embed it to share it with others. Another advantage is that you may work on tasks with other coworkers. However, one downside is that 3D LIDAR cannot be uploaded. It is, however, scalable.

  11. LabelMe

  12. This free machine learning image annotation tool allows you to identify pictures and videos for machine learning. It has numerous capabilities. It is possible, for example, to draw rectangles around a shape, a box, or lines. One disadvantage is that you must utilize the JSON format. You must also be familiar with Python.

  13. VoTT

  14. VoTT is a free online image annotation tool that allows you to add text, highlight features, and put shapes into photographs. Because it is free and open-source, the annotation picture tool is excellent for those on a tight budget. It is feasible to import and export data via cloud service providers. Microsoft, however, no longer supports the system.

  15. CVAT

  16. CVAT is a user-friendly browser image annotation tool from Intel. It is available for free online. Image annotation software for computer vision allows you to add words, lines, and shapes to pictures. Computer vision labeling is possible using the video annotation tool. There is also semi-automatic annotating.

  17. Labelbox

  18. The ai-assisted label image annotation application can rapidly and reliably tag photos and videos on any device. Labelbox is simple to use and offers a wide range of possibilities. Semantic segmentation, quality control, and performance analytics are among the features. However, you must purchase advanced features.

Final Thoughts

In AI and machine learning, appropriately training data delivers the highest-quality outputs. The finest image annotation tools for the assignment are those that coincide with the aims of your computer vision project.
