Syntax Directed on-Line Recognition of Cursive Writing

A syntax organization for recognition of handwritten connected-word is studied in the work. Each writing is cut into strokes at the middle point of every down cave of the writing, and the strokes are named using their directional characteristics and relative size among the strokes. A syntax is organized using the hierarchy of the stroke characteristics and self-iteration for the error corrections. The strokes are classified by the hierarchy and processed to combine the strokes into characters by the hierarchical characteristics. The lowest level of hierarchy collects those strokes which can not be combined into characters by their solid stroke characteristics and organizes a two dimensional family relation for relative combination of the strokes into characters. The local classifying routines are called for those stroke relations which require the evaluation of the relative characteristics between the strokes for the optimal decision. (Author)
