react-annotation-tool
A react based video & image annotating tool.
Quick Start
Installation
Use npm to install the tool into your react project.
npm i react-annotation-tool --save
Usage
Two tools are available now. They are Image Annotation Tool (aka TwoDimensionalImage) and Video Annotation Tool (aka TwoDimensionalVideo) respectively. Import either one into your react component.
import {TwoDimensionalImage, TwoDimensionalVideo} from "react-annotation-tool"
Image Annotation Tool
This tool allows to annotate images with polygons. Users could create new taxonomy if they feel the annotation does not fit into any default options. It is adopted by a CVPR 2019 paper, VizWiz-Priv: A Dataset for Recognizing the Presence and Purpose of Private Visual Information in Images Taken by Blind People.

| Parent(parentName) | If you enable Split functionality, this property stores the parent who generates current annotation |
| Children(childrenNames) | If you enable Split functionality, this property store the children belong to current annotation |
