摘要
针对在路面检测中传统中值滤波方法存在的不足,依据沥青路面病害图像特征分析,提出了准米字窗口中值滤波算法,并将该算法应用于沥青路面病害图像处理;仿真结果表明:准米字窗口中值滤波算法在有效抑制噪声的同时最大可能地保留了图像中病害的边缘细节信息,检测精度高,计算量小;较传统中值滤波具有更优的综合滤波性能,对沥青路面病害图像有更强的适用性。
To overcome the drawbacks of the standard median filter when applied for the road detecting,the median filter with improved all direction windows is proposed.The algorithm is based on the analysis of the bitumen pavement diseases image feature.It is used for processing the bitumen pavement diseases image.Simulation results show that the method can suppress noise effectively while preserving the diseases details very well.It is accurate and simple.It has better filtering performance and adaptability for the bitumen pavement distress image than the standard median filter.
