Detection of direction deviation of vehicle using CCTV cameras

As an application of CCTV Traffic surveillance, detection of direction deviation of vehicle is an important dimension, which demands an intelligent solution. It is assumed that images of vehicles have been captured at a particular orientation i.e. from top view and top-front view using CCTV cameras installed at junction along a particular road at an instant. When CCTV cameras are installed at junction for real time traffic surveillance system, a lot more information can be retrieved from the captured traffic images which can be further utilized for intelligent traffic system. The key technique used to develop this work is image processing. This document presents a new work on traffic image, in which the traffic image is processed to find out if every individual vehicle is going in the straight or diagonal direction when it crosses the junction. Intensity values are computed on each pixel in row and column. These intensity change values are used to calculate x-extent and y-extent of vehicle which results the direction of vehicle, either the vehicle is moving in straight direction or moving in diagonal direction.
