  • Segmentation process for machine reading of handwritten information
    Patent number: 5101439
    Abstract: An improved machine process for recognizing the transition point between letters and digits in handwritten text is disclosed. The script, digits and/or letters, is mapped onto a pixel matrix. The entropy for each column for a range of assumed slant angles is analyzed to determine the angle at which image entropy is a minimum. By reverse-shifting the pixel array an amount equal to this angle, the slant component of the script is verticalized and the segmentation step which follows is more accurately accomplished.
