Auto-line-division system for handwriting manuscript for line-division of a handwriting manuscript from an electronic handwriting input panel

A method of dividing a document handwritten on an input panel device into lines, comprising: recording stroke coordinates and stroke time data S110; calculating a standard line height and width S115; deleting abnormal strokes in the manuscript that are above a multiple of the standard line height or width S120; pre-dividing the script into coarse or rough lines using the standard line height and width S125; setting each isolation point and reversal stroke as a single line S130; re-dividing overly large lines that are greater than a set multiple of the standard line height S135; determining whether the standard line division is correct and redistributing lines as needed S140-S145; and determining if the space between two strokes is large enough as to indicate a line boundary and splitting the strokes into different lines S150. The standard line height and width may be used to determine whether the document comprises a single word S155, S165, S170. The line height and line width may be based on a ratio taken from all stroke heights and stroke widths respectively. Re-dividing the lines may comprise using a clustering algorithm on the maximum stroke heights.
