    This study presents an automated algorithm for segmenting PAP-stained cell images. The digital implementation effectively separates cell nuclei and cytoplasm from the background using image filtering and gradient analysis.

    Area of Science:

    • Digital image processing
    • Cell biology
    • Medical imaging analysis

    Background:

    • Accurate cell image segmentation is crucial for quantitative analysis.
    • Manual segmentation is time-consuming and prone to subjectivity.
    • Existing automated methods may struggle with image noise and object variability.

    Purpose of the Study:

    • To develop and implement an automated algorithm for segmenting PAP-stained cell images.
    • To accurately differentiate between nucleus, cytoplasm, and background.
    • To enable quantitative analysis of cellular components.

    Main Methods:

    • Image filtering to remove noise and small objects.
    • Extraction of gradient and compactness information using histograms.
    • Computation of extinction thresholds for segmentation.
