Since the image segmentation can be considered as a type of classification, SVM can be designed as an efficient image segmentation tool. This thesis aims to develop a SVM based intelligent road transportation control system, which involved three modules: pavement inspection, vehicle tracking, and collision warning. In the pavement inspection part, the SVM is used to extract the pavement from the background in a given image. The Radon transform is then applied to the pure pavement image to classify the crack to a particular type. In the vehicle tracking part, SVM trained by Gabor and edge features is involved to segment the first frame of a given video, which captured by an in-car camera. Another Wavelet feature based SVM is utilized to tracking this specific vehicle. In the collision warning part, the Time to Collision (TTC) is calculated by the scale change method. By the comparison between the TTC and a predefined threshold value, the Forward Collision Warning (FCW) system is designed, which can inform the driver to push the brake to avoid crash. Although the traditional image processing methods can fulfill all the three tasks above, limited success has been accomplished due to the low accuracy of image segment result. The proposed SVM algorithm can be trained by the proper feature, such as RGB feature, Gabor feature, Wavelet feature, etc., which makes the system appear to be more effective and computationally more efficient. 2012 English text University of Toledo / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=toledo1352749656 http://rave.ohiolink.edu/etdc/view?acc_num=toledo1352749656 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
