Toronto’s CN Tower is the world tallest freestanding tower structure. Built between 1973 and 1975, this giant communication and observation tower represents the extensive design process that lasted six years. The structural design of the Tower was one of the major challenges of design process.

The City of Edmonton is currently in need of an automatic passenger counting (APC) system for its Light Rail Transit (LRT). An APC will help the City with various decisions making. In this proposal we focus on automatic video processing to count passengers boarding and alighting from LRT. The proposed system is simple – it will consist of overhead inexpensive IP cameras directly looking down at the car doors. Direct top view will be able to avoid occlusions.
