On-line handwriting recognition using Chain Code representation

When one preparing a first draft, concentrating on content creation or summarizing lecture notes, pencil and paper are often favored over the keyboard. Although in some cases (e.g. when copying text into a document or trying to organize written text) keyboard has a significant advantage over handwriting, in others it can cause difficulties, e.g. when writing lecture notes when equations, graphs and other marks are required. Also, when writing text, the keyboard is faster than handwriting for small alphabet languages, however for large-alphabet languages, like Chinese, keyboards are cumbersome. In these cases, where writing is favored, handwriting recognition offers the alternative's advantages.
