Set up an account on the Moodstocks developer platform and create an API key for your application:
 
- convenient web interface,
- API key creation in one-click,
- pointers to the various docs.

Index your reference images into the Moodstocks API and flag the visuals you wish to recognize offline:
 
- fully documented, simple-to-use HTTP API,
- handy bash client,
- code snippets in all languages (Ruby, Python, PHP, etc)

Set up the SDK into the client application, and synchronize the image signatures into an offline cache database:
 
- persistent cache saved on-disk,
- smart incremental sync that runs in the background,
- highly optimized network operations.

Process the video capture, perform real-time searches thanks to the offline cache, and display results within an overlay:
 
- blazing fast searches (several FPS),
- user-defined overlays with info / actions,
- barcode decoding integrated (EAN / UPC-A / QR Code).
