Hierarchical System for Recognition of Traffic Signs Based on Segmentation of Their Images

This article proposes an algorithm for recognizing road signs based on a determination of their color and shape. It first searches the edge segment sign. The boundary curve sign is defined by segment. Approximating boundaries reveals its hierarchical recognition system forms classes in form Six are at level. Two contain only one Signs classified second level hierarchy. image inside cut third then identified comparison pattern. A computer experiment was carried out two collections signs. proposed has high operating speed low percentage errors.
