Abstract A vehicle detection approach based on Gabor feature and multiresolution hypothesisverification structure is proposed. The proposed approach includes two basic phases. Firstly, the Regions of Interest (ROI) in an image are determined according to the lane vanishing points. Then a hypothesis list in each ROI is created according to the vertical edges and horizontal edges. Finally, a hypothesis list for the whole image is obtained by combining these three lists. In the hypothesis validation phase, a vehicle validation approach using Support Vector Machine (SVM) is proposed. The proposed algorithm decreases the computational cost by eliminating uninteresting area, and in the hypothesis verification phase, the positive false is low. The experimental results show that the average right detection rate reaches 90% and the execution speed is 20fps using a Pentium(R)4 CPU 2.4GHz.
