VGG Image Annotator JSON

The VGG Image Annotator tool's JSON format.

Overview

The Visual Geometry Group (VGG) at the University of Oxford released an open source annotation tool called VIA (VGG Image Annotator). It outputs its labels to CSV or JSON; Roboflow supports importing both and converting them to any other object detection format you like.

See our VGG Image Annotator Tutorial to learn how to use VIA to create object detection annotations.

Format Description

Below, learn the structure of VGG Image Annotator JSON.
