Vehicle Velocity Detection:
I had done this project as my MSc project in University. We started that because of a problem of Iranian Police Force in detecting speed of cars in highways and roads using old Sonar and Laser sensors. The problem that, sometimes the sensor mistakes and assumes front weels of a car (say Car 1) and rear weels of another car (say Car 2) as a Car. So, it reports an invalid speed. We experienced following features in development of this project:

• Object Tracking and Extraction
• Different Background Modeling techniques, and presenting new techniques
• Real world mapping and extracting real position of objects using Homography and Inverse Prespective Mapping
• Extracting Velocity of objects in scene
• Recording result of algorithm in AVI files using libquicktime
• Using SDL for presenting result of algoithm in graphical window (Realtime)
  

By presenting techniques used in this project, we published three papers in different conferences:

• R Zabihollahi, M Soryani, "Vehicle Velocity Detection System Based on Real-Time Motion Tracking," Accepted by Machine Vision and Image processing, 2007.
• R Zabihollahi, M Soryani, "Vehicle Shadow Exclusion for a Vehicle Velocity Detection System," Submitted to International Multi-Conference of Engineers and Computer Scientists, 2007.
• R Zabihollahi, M Soryani, "Edge based tracking," Submitted to Iranian Conference on Electrical Engineering, 2007.
