摘要
车辆局部特征提取是车辆检测的关键。目前常使用的一些特征提取方法不够稳定,且容易丢失图像局部特征。提出基于2D Gabor滤波器的车辆局部特征提取方法,分析并探讨滤波器方向、径向中心频率以及滤波窗口大小对图像结果的影响。Matlab仿真结果证明该方法的有效性。
Feature extraction of the local vehicle is the key of vehicle detection.Some method commonly used for the current feature extraction is not stable,and easy to lose local image features,The method of feature extraction of the local vehicle based on 2D Gabor filter was introduced,the fluence of fliter direction,radial center frequency and size of fliter windows to simulation results are analysed and discussed.Matlab simulation results prove the effectiveness of the method.
