Get started

Download the plugin with the method of your choice.

• Download the last release manually

    bower install jquery.facedetection 

• Or install it with NPM.

    npm install jquery.facedetection 

Include jQuery and the plugin.

<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script> <script src="path/to/dist/jquery.facedetection.min.js"></script> 

Set a picture with some faces in your HTML page.

<img id="picture" src="img/face.jpg"> 

Apply the plugin to this image and get the face coordinates.

<script>     $('#picture').faceDetection({         complete: function (faces) {             console.log(faces);         }     }); </script> 

Results

Returns an array of found faces object:

• x — X coord of the face in the picture
• y — Y coord of the face in the picture
• width — Width of the face
• height — Height of the face
• positionX — X position relative to the document
• positionY — Y position relative to the document
• offsetX — X position relative to the offset parent
• offsetY — Y position relative to the offset parent
• scaleX — Ratio between original image width and displayed width
• scaleY — Ratio between original image height and displayed height
• confidence — Level of confidence

Settings

• interval — Interval (default 4)

• minNeighbors — Minimum neighbors threshold which sets the cutoff level for discarding rectangle groups as face (default 1)

• confidence — Minimum confidence (default null)

• async — Async mode if Worker available (default false). The async mode uses Workers and needs the script to be on the same domain.

• grayscale — Convert to grayscale before processing (default true)

• complete — Callback function trigged after the detection is completed

    complete: function (faces) {       // ...   } 

• error — Callback function trigged on errors

    error: function (code, message) {       // ...   }
