Compretend

Web application building blocks power by ML.

This repo contains:

• An API service.
• WebComponents that rely on the API service.

Usage

Include compretend on your web page.

<script src="https://cdn.jsdelivr.net/npm/compretend/dist/compretend.min.js"></script>

Now you can add compretend elements to your page.

<compretend-img src="http://site.com/image.png" crop="faces">
</compretend-img>

The above example will place an image on the page centered around the faces detected in the image.

Detection

Currently available detection APIs are:

• faces: Front and profile faces detection.
• people: Detection of people by full body, upper torso, and lower torso.

Components

Compretend components have many properties. These properties can be set as element attributes or with JavaScript.

let elem = document.querySelector('compretend-image')
elem.crop = "faces"
elem.width = 320

Displays an image. Image data can be set by either specifying the "src" attribute or setting the "data" property to an ArrayBuffer or Blob.

• src: URL to remote image. Can be on any publicly available server.
• data: ArrayBuffer or Blob representing image data.
• crop: String for detection method.
  • Detected attributes in the image will be centered within the constraints set of width/height. If width/height are not set the image is cropped around the detected elements.
• width: Image element width.
• height: Image element height.
• scaled: Scale image down to the specific dimensions (height and width). Defaults to false.
• margin: Ads margin to a cropped and scaled image.

REST API

All APIs require a body. This can be an HTTP PUT/POST body or it can be a querystring identifier (hash or remote URL).

/images/detect/faces

Accepts only the body argument.

Return JSON of all facial detections.

/images/detect/people

Accepts only the body argument.

Return JSON of all people detections.

/images/generate

Returns generated image data as PNG.

Accepts the following querystring parameters:

• body: Hash or remote URL. Optionally defined as a PUT/POST body.
• crop: Detection method to use for crop boundary detection. faces and people currently implemented.
• width: Image element width.
• height: Image element height.
• scaled: Scale image down to the specific dimensions (height and width). Defaults to false.
• margin: Ads margin to a cropped and scaled image.

/images/bounds

Returns JSON data describing the crop boundaries for the given query.

Accepts the following querystring parameters:

• body: Hash or remote URL. Optionally defined as a PUT/POST body.
• crop: Detection method to use for crop boundary detection. faces and people currently implemented.
• width: Image element width.
• height: Image element height.
• scaled: Scale image down to the specific dimensions (height and width). Defaults to false.
• margin: Ads margin to a cropped and scaled image.
