Comparative Model Performance
A cross-dataset comparison revealed systematic differences in classification performance driven by feature origin and integration. Logistic Regression consistently delivered strong performance across various feature sets.
| Metric | CV-RCNN (Logistic Reg.) | CV-YOLO (Logistic Reg.) | Combined CV (Logistic Reg.) | ALL (Logistic Reg.) |
|---|---|---|---|---|
| Test Accuracy | 96.92% | 90.77% | 95.38% | 93.85% |
| Weighted F1-Score | 0.9690 | 0.9066 | 0.9530 | 0.9380 |
| Inference Time (ms/image) | 2327.42 | 142.94 | N/A (combined inference) | N/A (combined inference) |
| Parameters (Millions) | 43.9 | 3.26 | N/A (combined models) | N/A (combined models) |
Key Takeaway: R-CNN offers superior classification accuracy due to its precise segmentation, while YOLOv8 provides a significant speed advantage, making it suitable for real-time edge deployments where slight accuracy trade-offs are acceptable. Combining features consistently enhances robustness.
Insights from Feature Analysis
Multivariate analyses, including PCA and correlation networks, revealed distinct patterns in how R-CNN and YOLOv8 extract phenotypic information, and how combining these features enhances discriminability.
R-CNN
Captures nuanced colorimetric and structural variations, providing high fidelity in trait representation, crucial for fine-grained ripening stages.
YOLOv8
Emphasizes morphological characteristics and excels in object completeness, offering efficiency for generalized object delineation.
The clear delineation of features into morphological and colorimetric contributions supports a biologically meaningful dual-axis model of ripening. Integrated PCA frameworks reaffirm the advantage of R-CNN-based features for trait fidelity and classification robustness in image-based trait modeling.
Real-World Performance: Navigating Environmental Complexity
To assess practical applicability, a preliminary field validation was conducted using raw images from diverse agricultural environments. This evaluation tested the transferability of our framework beyond controlled laboratory settings.
Field Validation Outcomes
Despite not being retrained or fine-tuned for field data, the proposed segmentation and classification framework achieved classification precision approaching 83% for individual feature sets. This represents a performance degradation compared to the lab (e.g., R-CNN 96.92% in lab vs. ~82.46% in field).
Challenges & Insights: The performance drop is primarily attributed to domain shift and dataset bias, encompassing variable illumination, heterogeneous backgrounds, occlusions, and fruit overlap common in real-world agricultural images. These factors affect segmentation fidelity, leading to perturbed feature extraction. However, the consistent performance of SVM and Logistic Regression models highlights their intrinsic robustness to feature noise, demonstrating the practical potential of these solutions even without extensive field-specific retraining.
This underlines the need for future work in domain adaptation and mixed-environment training to enhance generalizability for true real-world deployment.
