| Abstract(in English) | A novel algorithm for the recognition of Japanese road sign symbols with red annular boundaries is proposed. After detecting a red annular object using HSB color coordinates, a biologically inspired opponent-color filter is applied to extract the symbol parts of road sign. By applying discriminant analysis to the filter output, the inside region circumscribed by red annular boundary can be extracted. By applying the discriminant analysis again to the inside region, the symbol part of road sign can be segmented. The segmented symbol is classified by a decision tree and recognition rate of about 96% achieved. |
