About the Project
Transforming the leisure and tourism photography experience: Powered by patented technology, our platform combines advanced association methods with an AI learning engine to enable real-time media streaming at scale, without compromising guest privacy.
The platform uses AI to recognize individuals within crowded and dynamic environments such as amusement parks and events, allowing guests to simply upload a selfie to match it with media captured in real time. The platform automatically associates all relevant photos and videos with a user and delivers them directly to their device.
