    This study introduces a novel fuzzy thresholding method using 2-D histograms for image segmentation. The proposed fuzzy approach significantly improves segmentation accuracy compared to nonfuzzy and 1-D methods.

    Area of Science:

    • Computer Vision
    • Image Processing
    • Artificial Intelligence

    Background:

    • Image segmentation is a critical step in image analysis.
    • Traditional thresholding methods often struggle with complex image features.
    • Fuzzy logic offers a robust framework for handling uncertainty in image data.

    Discussion:

    • The proposed method utilizes a two-dimensional (2-D) histogram for enhanced feature representation.
    • Fuzzy partitioning based on fuzzy relations and maximum fuzzy entropy optimizes threshold selection.
    • Experimental validation on diverse datasets confirms the efficacy of the fuzzy approach.

    Key Insights:

    • The novel fuzzy thresholding technique achieves superior performance over existing 2-D nonfuzzy and 1-D fuzzy methods.
