CrowdCurio / image-annotator

An image annotation library.

CrowdCurio Image Annotator Library

The CrowdCurio Image Annotation Library implements counting (classification) and transcription tasks for images.

"The interface is so mature." - Hemant Surale.

Features

• Support for counting and (letter-by-letter) transcription tasks.
• Support for alternating between practice tasks and required tasks.
• Zoom functionality.
• Fullscreen functionality.
• Integrated support for CrowdCurio.

Build Process

We use Browserify and Uglify in our build processes. Both tools can be installed with NPM.

npm install -g browserify

npm install -g uglify-js

To build the script bundle without minification, run:

browserify lib/main.js -o bundle.js

To build with minification, run:

browserify lib/main.js | uglifyjs bundle.js

Usage

The UI is controlled by a set of parameters upon instantiation. Here's an example of the configuration and its usage:

// transcription configuration
var config = {
    mode: 'transcription',  # required
    language: 'greek',      # required
    practice: {
        active: false
    }
}

// counting configuration
window.config = {
            mode: 'counting',
            labels: [{
                name: 'Tau',
                examples: [
                    'url1',
                    'url2',
                    'url3'
                ]
            }, {
                name: 'Nu',
                examples: [
                    'url1',
                    'url2',
                    'url3'
                ]
            }],
            practice: {
                active: true,
                feedback: true
            }
        };

// define a new annotator
var annotator = new ImageAnnotator();
annotator.initialize(config);
