The library can detect the features supported by the browser and help write web applications with Image Recognition.

Your apps can seamlessly switch between two modes:

The Image Selector:

HTML element that asks the user to select an image from the gallery, OS’s camera (by asking the user to take a picture with the device’s built in camera app) or file system.

The camera Capture:

Open the device’s camera or webcam and show the preview. This mode allows you to perform Cloud Image Recognition in two modes:

  • Single shot: Take a picture and search.
  • Finder Mode: Send continuous queries to the server until a result is found or the process is stopped programmatically.


You can find documentation for the library here


You can view live demos for each example by clicking on the buttons below. The source code of those examples is part of the library package.


Multi Mode

Detects if camera capture is supported by the browser. Opens capture if it is supported, otherwise it falls back to selecting an image from the library or opening the camera app.



Tries to open the camera assuming it is supported in the browser. If it is not supported in the browser, it gives an alert.


Selector example

Select an image by taking a photo or uploading one from the device’s library.

For the examples that open the camera you’ll need to print the test images below to test them. For the Selector, you can just download them. As the result of a successful recognition, the name of the item appears listed.
