Tire Tread Pattern Recognition and Feature Analyzing Based on Hu Moment

This paper aims to recognize the tire tread pattern from DXF (Drawing Interchange Format) file and to analyze its basis feature. A DXF file analyzing algorithm is used to obtain the data according to the formulate of DXF; a feature analyzing approach based on Hu moment is utilized to compute the seven characteristic moments and to confirm the invariance of pattern image under image rotation, scaling, and translation; a feature analyzing system is developed by Java to show the basic feature. The experimental results show that the proposed system has a good achievement and can get a series of ideal parameters for the further research.
