In order to correctly extract the line-features of symbols and some of their attributes
Hough transformation has been improved based on the analysis of its limitations
and it has therefore the additional inspection of line continuity and extraction of associated attributes
such as number
direction (angle)
start and finish of lines. Experimental results show that the algorithm proposed can be used to extract symbol lines and some of their attributes
and it can be used for extraction of symbol features in other recognition systems as well.
