    Accurate segmentation of rat liver tissue in histopathology images is vital. This study developed methods using contrast enhancement, compactness, and skeletonization algorithms for precise nuclei, nucleoli, and cell separation.

    Area of Science:

    • Histopathology
    • Image Analysis
    • Computational Biology

    Background:

    • Quantitative histopathology relies on accurate image segmentation.
    • Segmentation of cellular components like nuclei and nucleoli is challenging.
    • Existing methods may lack precision for specific tissue types.

    Purpose of the Study:

    • To investigate and optimize segmentation methods for rat liver tissue.
    • To achieve precise separation of nuclei, nucleoli, and whole cells.
    • To enhance quantitative analysis in histopathology.

    Main Methods:

    • Applied contrast-enhanced polar-coordinate transformation for nuclei segmentation.
    • Utilized a compactness algorithm for nucleoli identification.
    • Employed a skeletonization algorithm for cell boundary delineation.

  • Incorporated a priori morphometric and photometric data of liver tissue.

    • Main Results:

    • Achieved reasonable segmentation of nuclei using contrast enhancement.
    • Successfully distinguished nucleoli with the compactness algorithm.
    • Effectively delineated whole cells via skeletonization.
    • Demonstrated improved segmentation accuracy with integrated tissue properties.

    Conclusions:

    • The developed segmentation approach provides effective tools for liver tissue analysis.
    • Combining specific algorithms with prior tissue knowledge enhances segmentation accuracy.
    • This method supports advanced quantitative histopathology and biomedical research.
