The SDK ships with a simple example application that demonstrates how to set up an object tracker, how to feed it with video frames from a camera, and how to receive information about detected and recognized persons from the object tracker.
The demo application requires an active SAFR cloud account in order to function. Search for the $USER and $PWD in the source and replace them with your SAFR account user name and password. The demo source will not compile until you've updated it with your SAFR credentials.
