Abstract
This article presents a digital image processing algorithm to estimate a vehicle speed using Lucas-Kanade Optical Flow. It was calibrated using images with known car speeds. The optical flow algorithm was improved with some statistical operations to refine the results for this specific case. The simulated results showed an acceptable average error.
