    Discussion:

    • This study introduces novel wavelet-based feature sets for texture analysis.
    • Wavelet histogram signatures capture first-order statistics.
    • Wavelet co-occurrence signatures capture second-order statistics.

    Key Insights:

    • Wavelet signatures significantly outperform traditional energy features for texture characterization.
    • Combining first-order (histogram) and second-order (co-occurrence) wavelet statistics yields optimal performance.
    • The proposed method offers a robust approach to texture analysis.
