Spotted Lanternfly Egg Mass Detection via Texture Features

Karla Negrete's 2026 figshare publication presents a proof-of-concept automated image classification pipeline for detecting invasive spotted lanternfly egg masses. The method uses a support vector machine trained on 12 selected spatial texture features, achieving a mean Matthews Correlation Coefficient of 0.881 in cross-validation. The work aims to support scalable, low-cost surveillance in high-risk transport corridors.

Use Cases

• Train a support vector machine classifier on 12 selected spatial texture features for binary image classification of egg masses.
• Implement a feature filtering and selection strategy using Gray-Level Co-occurrence Matrix (GLCM) and Gray Level Difference Statistics (GLDS) descriptors to build an interpretable model.
• Evaluate model generalization performance using bootstrap resampling (1,000 iterations) on a held-out test set, reporting the mean MCC and confidence interval.
• Apply Hu and Zernike moments as image descriptors within a computer vision pipeline for automated pest surveillance in agricultural settings.

Strengths

• The final classifier achieved a high mean Matthews Correlation Coefficient of 0.881 under 5-fold stratified cross-validation.
• Model generalization was rigorously tested with 1,000 bootstrap iterations on a held-out test set.
• The method is based on 12 selected spatial texture features, creating a low-dimensional and interpretable model.

Limitations

• The dataset is a curated laboratory image set; performance in uncontrolled, real-world field conditions is unvalidated.
• The publication is a proof-of-concept; the underlying image dataset itself is not provided, only the methodological description and results.
• The 7.4 MB file contains a PDF document, not a directly usable tabular or image dataset for model training.
