Algorithm on Vehicle Tracking and Speed Estimating Based on Non-Calibrated Camera

This algorithm extracts moving vehicles using median filter,frame differencing and image Boolean calculation,resumes part of losing pixels using mathematical morphology,calculates the centroids of vehicles by obtaining the minimum exterior rectangle of the moving edges,processes the resulting edge information to obtain quantitative geometric measurements of vehicles.The results presented demonstrate the validity of this algorithm which requires neither direct camera control nor placement of a calibration object in environment.
