Hausdorff Distance techniques have been proposed for
Thai CLP. The experimental results reveal high percentage
of recognition accuracy. From 450 real CLP image
examples employed in this research, the system could
perform valid recognition for 412 CLP image that is 92%.
However, more research has to be conducted to get high
performance even for poor quality images and among
groups of similar-pattern characters (e.g. “” and “«”, “”
and “”, “” and “£”, “” and “®”).
