Abstract
A method and apparatus for effecting character segmentation in a cursive script handwriting analysis system which comprises obtaining the continuous x and y coordinates and the x and y velocities of a writing instrument forming said cursive character. Continuously averaging the x displacement associated with all the x and y extremal points of a handwritten character where the x or the y velocity equals zero. Successively examining the x displacement for each x-extremal and determining if the x displacement of said extremal exceeds a predetermined threshold value relative to the average x displacement of the current character and if so indicating that said new extremal is located in the next character and that a segmentation mark should be placed at a predetermined distance along the ligature between the just analyzed extremal and the previously analyzed extremal. The results of this segmentation are then communicated to a character recognition mechanism whose efficiency and accuracy is greatly enhanced by said segmentation indication. The system as designed is also able to follow deviations from the baseline and mid-zone line as the writing progresses.
