Abstract
This paper focus on the problem of recognizing 28 kinds of motored and non-motorized hand-drawn vehicle symbols which are commonly used in traffic accident description.To solve the problems of the irregular transformation of sketch vehicles and similarity among different vehicles during recognition,an elastic meshes HOG feature is proposed.In this feature,horizontal and vertical projection histogram which is a good choice for global features is used to calculate the elastic meshes,and then elastic meshes combine with HOG feature instead of HOG's cells for absorbing deformation.The total recognition rate reaches 94.8％ in our set of samples,and 92.5 ％ for different areas of the pen digits,common diagram shapes,and electrical circuit symbols.The experimental results show that:our proposed algorithm has a high recognition rate for the hand-drawn vehicle symbols and it has a good promotion prospects.关键词
