# Computer Vision Annotation Tool (CVAT) [![CI][ci-img]][ci-url] [![Gitter chat][gitter-img]][gitter-url] [![Coverage Status][coverage-img]][coverage-url] [![server pulls][docker-server-pulls-img]][docker-server-image-url] [![ui pulls][docker-ui-pulls-img]][docker-ui-image-url] [![DOI][doi-img]][doi-url] CVAT is free, online, interactive video and image annotation tool for computer vision. It is being used by our team to annotate million of objects with different properties. Many UI and UX decisions are based on feedbacks from professional data annotation team. Try it online [cvat.org](https://cvat.org).  ## Documentation - [Installation guide](cvat/apps/documentation/installation.md) - [User's guide](cvat/apps/documentation/user_guide.md) - [Django REST API documentation](#rest-api) - [Datumaro dataset framework](https://github.com/openvinotoolkit/datumaro/blob/develop/README.md) - [Command line interface](utils/cli/) - [XML annotation format](cvat/apps/documentation/xml_format.md) - [AWS Deployment Guide](cvat/apps/documentation/AWS-Deployment-Guide.md) - [Frequently asked questions](cvat/apps/documentation/faq.md) - [Questions](#questions) ## Screencasts - [Introduction](https://youtu.be/JERohTFp-NI) - [Annotation mode](https://youtu.be/vH_639N67HI) - [Interpolation of bounding boxes](https://youtu.be/Hc3oudNuDsY) - [Interpolation of polygons](https://youtu.be/K4nis9lk92s) - [Tag annotation video](https://youtu.be/62bI4mF-Xfk) - [Attribute mode](https://youtu.be/iIkJsOkDzVA) - [Segmentation mode](https://youtu.be/9Fe_GzMLo3E) - [Tutorial for polygons](https://youtu.be/C7-r9lZbjBw) - [Semi-automatic segmentation](https://youtu.be/9HszWP_qsRQ) ## Supported annotation formats Format selection is possible after clicking on the Upload annotation and Dump annotation buttons. [Datumaro](https://github.com/openvinotoolkit/datumaro) dataset framework allows additional dataset transformations via its command line tool and Python library. For more information about supported formats look at the [documentation](cvat/apps/dataset_manager/formats/README.md#formats). | Annotation format | Import | Export | | ----------------------------------------------------------------------------- | ------ | ------ | | [CVAT for images](cvat/apps/documentation/xml_format.md#annotation) | X | X | | [CVAT for a video](cvat/apps/documentation/xml_format.md#interpolation) | X | X | | [Datumaro](https://github.com/openvinotoolkit/datumaro) | | X | | [PASCAL VOC](http://host.robots.ox.ac.uk/pascal/VOC/) | X | X | | Segmentation masks from [PASCAL VOC](http://host.robots.ox.ac.uk/pascal/VOC/) | X | X | | [YOLO](https://pjreddie.com/darknet/yolo/) | X | X | | [MS COCO Object Detection](http://cocodataset.org/#format-data) | X | X | | [TFrecord](https://www.tensorflow.org/tutorials/load_data/tfrecord) | X | X | | [MOT](https://motchallenge.net/) | X | X | | [LabelMe 3.0](http://labelme.csail.mit.edu/Release3.0) | X | X | | [ImageNet](http://www.image-net.org) | X | X | | [CamVid](http://mi.eng.cam.ac.uk/research/projects/VideoRec/CamVid/) | X | X | | [WIDER Face](http://shuoyang1213.me/WIDERFACE/) | X | X | | [VGGFace2](https://github.com/ox-vgg/vgg_face2) | X | X | | [Market-1501](https://www.aitribune.com/dataset/2018051063) | X | X | | [ICDAR13/15](https://rrc.cvc.uab.es/?ch=2) | X | X | ## Deep learning serverless functions for automatic labeling <!--lint disable maximum-line-length--> | Name | Type | Framework | CPU | GPU | | ------------------------------------------------------------------------------------------------------- | ---------- | ---------- | --- | --- | | [Deep Extreme Cut](/serverless/openvino/dextr/nuclio) | interactor | OpenVINO | X | | | [Faster RCNN](/serverless/openvino/omz/public/faster_rcnn_inception_v2_coco/nuclio) | detector | OpenVINO | X | | | [Mask RCNN](/serverless/openvino/omz/public/mask_rcnn_inception_resnet_v2_atrous_coco/nuclio) | detector | OpenVINO | X | | | [YOLO v3](/serverless/openvino/omz/public/yolo-v3-tf/nuclio) | detector | OpenVINO | X | | | [Object reidentification](/serverless/openvino/omz/intel/person-reidentification-retail-300/nuclio) | reid | OpenVINO | X | | | [Semantic segmentation for ADAS](/serverless/openvino/omz/intel/semantic-segmentation-adas-0001/nuclio) | detector | OpenVINO | X | | | [Text detection v4](/serverless/openvino/omz/intel/text-detection-0004/nuclio) | detector | OpenVINO | X | | | [SiamMask](/serverless/pytorch/foolwood/siammask/nuclio) | tracker | PyTorch | X | | | [f-BRS](/serverless/pytorch/saic-vul/fbrs/nuclio) | interactor | PyTorch | X | | | [Inside-Outside Guidance](/serverless/pytorch/shiyinzhang/iog/nuclio) | interactor | PyTorch | X | | | [Faster RCNN](/serverless/tensorflow/faster_rcnn_inception_v2_coco/nuclio) | detector | TensorFlow | X | X | | [Mask RCNN](/serverless/tensorflow/matterport/mask_rcnn/nuclio) | detector | TensorFlow | X | X | <!--lint enable maximum-line-length--> ## Online demo: [cvat.org](https://cvat.org) This is an online demo with the latest version of the annotation tool.
