'''Computer Vision Annotation Tool''' (CVAT) is aan [[Free and open-source software|free, open source]], [[Webweb application|web-based]] [[Listlist of manual image annotation tools|image and video annotation tool]] which is used for labeling data for [[computer vision]] algorithms. Originally developed by [[Intel]], CVAT wasis developeddesigned for use by a professional data annotation team, with a [[user interface]] optimized for computer vision annotation tasks.<ref>{{Citecite web |url=https://venturebeat.com/2019/03/05/intel-open-sources-cvat-a-toolkit-for-data-labeling/ |title=Intel open-sources CVAT, a toolkit for data labeling |date=2019-03-05 |website=VentureBeat |language=en-US |access-date=2019-08-13}}</ref> Try it online [https://cvat.org cvat.org].

CVAT supports the primary tasks of [[Supervisedsupervised learning|supervised machine learning]]: [[object detection]], [[image classification]], and [[image segmentation]]. CVAT allows users to annotate data for each of these cases.<ref>{{Citecite web |url=https://software.intel.com/en-content/www/us/en/develop/articles/computer-vision-annotation-tool-a-universal-approach-to-data-annotation.html |title=Computer Vision Annotation Tool: A Universal Approach to Data Annotation |date=2019-03-04 |website=software.intel.com |language=en |access-date=2019-08-13}}</ref>

CVAT has many powerful features, including [[interpolation]] of shapes between key frames, semi-automatic annotation using [[Deepdeep learning|Deep Learning]] models, shortcuts for most critical actions, a dashboard with a list of annotation projects and tasks, [[Lightweight Directory Access Protocol|LDAP]] and [[basic access authentication]], etc.<ref>{{Citationcitation |title=User's guide of Computer Vision Annotation Tool |date=2019-08-13 |url=https://opencv.github.com/opencvio/cvat/blobdocs/develop/cvat/apps/documentation/user_guide.md |publisher=OpenCVCVAT.ai |access-date=20192021-0807-1329}}</ref>

CVAT is written mainly in [[TypeScript]], [[React (webJavaScript frameworklibrary)|React]], [https://ant.design Ant Design], [[Cascading Style Sheets|CSS]], [[Python (programming language)|Python]], and [[Django (web framework)|Django]]. It is distributed under the [[MIT License]], and its source code is available on [[GitHub]].

CVAT team hosts an online version of the data annotation platform at cvat.ai as [[SaaS]].
