Team Leader, Desktop Developer2008 - 2010CrossShore
Technologies: .NET Forms, C#, C++, OpenCV. SentiSight, Socket Connections
- Created a full-scale application for a casino, used to detect card counters in blackjack. It was a huge project, gathering images from security cameras, recognizing objects, and maintaining their game strategies to detect "counting."
- Worked with video recognition software and machine learning. Switched to low-level libraries (OpenCV, C++) to get better performance, since camera resolutions were very high and the system was not able to recognize objects in real-time.
- Achieved 99.4% object recognition by implementing machine learning and training it by "watching" a series of game moves. The system was able to successfully recognize all cards (suits and value), money and chips, and auxiliary objects (dealer's hands, etc.), and to track moving objects from one zone to another.
- Implemented all known strategies for the game of blackjack. This is a huge work with lots of algorithms. Then all players are assessed against these strategies.
