III. FORWARD VEHICLE DETECTION AND TRACKING
The major part of the proposed system is FVDT function which flowchart is shown as Figure 2. Based on vanishing point and lane’s slopes from lane marking function, a ROI with five scan lines could be segmented for FVDT to detect if there is an obstacle or not. If there is an obstacle, then determine it is a vehicle or not. If it is a vehicle, then processes tracking function for the detected forward vehicle.
