Vehicle direction detection using symmetrical SURF and centroid point calculation

摘要

This paper proposed a new technique to determine the direction of a moving vehicle. In order to detect vehicles from road, concept of symmetrical descriptor is used to determine the ROI of each vehicle without using any motion features. This scheme proved to be advantageous as it does not require any background subtraction and efficiently works on real time applications. Once the vehicle is detected, the centroid of the vehicle is calculated to determine the direction of the vehicle. The major challenge in order to detect the direction is that the centroid point should also move along the direction of vehicle. This paper proposes the new concept of determining the centroid point through various SURF points of the vehicle.
