    This study clarifies that 2-D principal component analysis (PCA) and Fisher linear discriminant (FLD) are not strictly equivalent to block-based PCA and FLD. The correspondence highlights the lack of rigor in prior claims of equivalence for image-matrix feature extraction.

    Area of Science:

    • Computer Vision
    • Machine Learning
    • Data Science

    Background:

    • Image-matrix-based feature extraction algorithms are crucial for analyzing high-dimensional data.
    • Previous work suggested an equivalence between 2-D principal component analysis (PCA) and Fisher linear discriminant (FLD) and their block-based counterparts.

    Discussion:

    • This correspondence critically examines the assertion of equivalence between 2-D PCA/FLD and block-based PCA/FLD.
    • The analysis reveals that the claimed equivalence is not rigorously established in prior literature.
    • Potential discrepancies arise from the underlying mathematical assumptions and computational methodologies.

    Key Insights:

    • The statement regarding the equivalence of 2-D PCA/FLD and block-based PCA/FLD lacks rigorous mathematical justification.

  • Image-matrix feature extraction methods require careful consideration of their specific algorithmic properties.
  • This work emphasizes the need for precise definitions and proofs in algorithm comparisons.

    • Outlook:

    • Further research should focus on developing precise mathematical frameworks to compare different feature extraction techniques.
    • Investigating the practical implications of these distinctions in real-world applications is essential.
    • Clarifying these algorithmic relationships will advance the field of machine learning and computer vision.
