Self-Similarity based Zebra-crossing Detection for Intelligent Vehicle
Chao Wang, Chunxia Zhao, Huan Wang · The Open Automation and Control Systems Journal · 2015
A zebra-crossing detection method for intelligent vehicle is proposed in this paper.The method is performed on a bird-eye view image called inverse perspective mapping image.The complete method includes two phrases.First, a morphological filer followed by horizontal projection is applied to fast extract candidate zebra-crossing regions, where the size and structure information of zebra-crossing are well utilized.Second, a recognition method based on self-similarity is presented to identify the candidate regions.Given a seed region of a zebra-crossing, the recognition method can infer overall zebra-crossing region by matching and growing.Experiments on a great number of real images which consist of several challenge scenes demonstrate the effectiveness and efficiency of the proposed approach.
