Project Description and Goals
Design a high-speed trapezoidal image sensor and control system for continuous traffic monitoring at signalized intersection approaches

Problem Definition
Currently, obtaining position, speed, and acceleration information on cars in an intersection is a very costly process. It involves actual loops in the the road itself, radar, or the recently invented lidar. Additionally these applications require a lot of computing power and are thus slow. To monitor and control traffic in real time then, a solution that is faster and less expensive is needed. Additional info can be found on the Problem Definition Page.

Glossary of Terms
Rows -  Pixels that run from one side of the street to another perpendicular to the flow of traffic.

Columns -  Pixels that run up and down the street parallel to the flow of traffic.

Background -  A frame recording the unmoving parts of the scene.

Current Frame -  The frame being used to extract foreground objects.

Pixel Fill -  The portion of a pixels shade that can be attributed to a foreground object.

Delta Cap -  The maximum amount of change than can be applied to the background due to a new frame.

Delta Breach -  When a current frame pixel is more than one Delta Cap away from the corresponding background pixel.

Foreground Threshold -  The minimum difference between background and current frame pixels to register a foreground pixel.

Tripwire -  A row of pixels that is being monitored for foreground pixels.
