VoTT JSON

The native format of Microsoft's Visual Object Tagging Tool (VoTT)

Overview

VoTT (Visual Object Tagging Tool) is a popular open source annotation tool released my Microsoft. It lets you easily label image assets for use with object detection models. We have a full VoTT tutorial that shows the process of creating labels for your custom dataset.

The native format of VoTT is a proprietary JSON file that is not supported by any known models. Getting your VoTT-labeled dataset ready for training is where Roboflow comes in. Just import your images and annotations and select the format you want to convert it to and you'll be on your way to training a model in no time.
