Ecosystem overview: CVAT is coming

2 min read

CVAT (Computer Vision Annotation Tool) is a free, open-source annotation tool, branded as an Open Data Annotation Platform. CVAT is used by hundreds of companies and tens of thousands of users, and its Docker images were downloaded more than one million times.

The core team of CVAT previously worked at Intel, and joined to continue and expand development. As of this week, CVAT is relaunching its website and hosted version of the open-source tool, with plans for exclusive features in the future. They have published a new GitHub repository. The original repository for CVAT on GitHub had 7.6K stars! 

We have previously written about CVAT work becoming available on HUMAN Protocol. We are delighted to see that the CVAT team has made great progress in developing their app; we continue to work closely with the CVAT team as we seek to bring this work onto HUMAN.

A complement to the CAPTCHA tool currently running on HUMAN Protocol, CVAT is a sophisticated data labeling application that can produce granular and precise datasets for computer vision problems. Its integration will expand the capabilities of work available through the Protocol. A new data-labeling application potentiates extra benefits by virtue of network effects; applications running on the Protocol have a seamless avenue to share, connect, and check each other’s work.

About CVAT

Current CAPTCHA-based tools offer a relatively broad annotation – the images presented are divided into squares, or squares are filled with separate images; the items clicked upon are only as precise as the squares that frame the image. 

CVAT is a granular, sophisticated labeling application. It offers users a variety of more advanced labeling tools to annotate components of an image: users could use bounding boxes, polygons, freehands, and more to annotate an image with.

Significantly, CVAT includes automated and semi-automated annotation tools to highly increase the effectiveness of worker output.

We have discussed elsewhere one of the greatest prohibitors to the creation of truly useful AI products: the lack of specific and granular data available. CVAT’s system for annotating data provides the foundations for a solution. More detailed labeling tools can create more specific data sets, which can be used to create more specific functions for AI. Generalized AI is, after all, merely the accumulation of many specific functions (and adaptability to the environments in which they occur).

We highly anticipate such a powerful tool being integrated with HUMAN Protocol. 


HUMAN Protocol is a system designed to facilitate the automation, tokenization, evaluation and payment of work. In this sense, it is a system to unlock the future of knowledge workers. It is broadly applicable to many kinds of work, with a preliminary focus on data labeling. 

The recently announced Routing Protocol will operate as a coordination layer. It will establish a blueprint for voting, staking, slashing – and how, broadly, third party entities can be coordinated to help contribute to the process of work, such as tidying images before they are sent to a CAPTCHA or CVAT worker.
