This paper gives the results of an investigation on the use of exhaustive block matching techniques in detecting railway-line tracks in a video sequence with the view of implementing the outcome in a real-time system. The main focus of the research is to implement the exhaustive search block matching algorithm optimally and resolve any implementation problems that may arise. The algorithm is implemented on a video sequence that has undergone inverse perspective mapping. The second highlight of this research is to eliminate many video processing techniques, this is done in order to compensate for the computational expense for which the exhaustive search block matching algorithm is known for. The procedure entails traversing a very small block from the previous frame on the top and bottom ends of the current frame and marking the coordinates where the cost function is the minimum.
