react-annotation-tool

A react based video & image annotating tool. See demo.

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.

options

Nested array of object. Each object has id, value and children properties. Must start from object with value: "root". e.g.,

{id: "0", value: "root", children: [
   {id: "1", value: "Electronic", children: [
      {id: "1-1", value: "Laptop", children: [
         {id: "1-1-1", value: "Apple", children: []},         
         {id: "1-1-2", value: "Asus", children: []}  
      ]}, 
      {id: "1-2", value: "Charger", children: []},
      {id: "1-3", value: "Watch", children: []}
   ]},
   {id: "2", value: "Stationery", children: [
      {id: "2-1", value: "Pen", children: []},
      {id: "2-2", value: "Eraser", children: []}
   ]}
]}

disabledOptionLevels

Array of Integer. Start from "1". e.g.,

[1, 2]

Video Annotation Tool

Vidoe tool allows you to annotate object in videos via bounding box. The tool originally is designed for annotating cell videos.

Data Formats

Name	Description
Annotation	The basic unit of the annotation result
Incident	Each annotation contains mutiple incidents. Each incident records the time and some information (e.g., position, size, status...) when the annotation is manipulate by the users (e.g., split, move, resize...)
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

previewHeader	Header for preview	String	''
previewNoticeList	Content for preview	[String]	[]
isEmptyCheckEnable	Force users to annotate at least one object	Boolean	false
isSplitEnable	Enable Split button for each annotation	Boolean	false
isShowHideEnable	Enable Show/Hide button for each annotation	Boolean	false
hasReview	Enable review after users click submit button	Boolean	false
numAnnotationsToBeAdded	Number of annotations users can be added	Number	1000
