    The iterative cross section sequence graph (ICSSG) algorithm enhances handwritten character segmentation by iterative thresholding. This method improves optical character recognition (OCR) accuracy by preserving character structure.

    Area of Science:

    • Computer Vision
    • Image Processing
    • Pattern Recognition

    Background:

    • Handwritten character segmentation is crucial for Optical Character Recognition (OCR).
    • Traditional methods often suffer from information loss during image binarization.
    • Preserving character skeletal structure is key for accurate feature extraction.

    Discussion:

    • The iterative cross section sequence graph (ICSSG) algorithm applies iterative thresholding to segmentation.
    • This approach mitigates information loss inherent in standard image binarization.
    • ICSSG prevents pixel interference, preserving the integrity of individual character segments.

    Key Insights:

    • ICSSG effectively maintains the skeletal structure of handwritten characters.
    • Improved skeletal quality leads to enhanced feature extraction and classification.
