Optimization of line segmentation techniques for Thai handwritten documents

The purpose of the research is to study the optimization of line segmentation techniques for Thai handwritten documents. This research considered only single-column of Thai documents. The author proposed two new techniques including comparing Thai character and sorting and distinguishing. These two techniques were used with recognized techniques on the basis of projection profile (including horizontal projection profile and stripe) in the experiment. The outcome of this research suggested that the best technique for single-column Thai documents is the new technique for sorting and distinguishing, this technique provide the accuracy of 97.11%.
