Three-class segmentation shows 72.03% improvement in Dice coefficient 2. Three-class segmentation shows 99.70% improvement in IoU coefficient 3. Dice analysis confirms significant improvement 4. IoU analysis confirms significant improvement 5. Post-processing provided substantial improvements in both scenarios FILES GENERATED: ---------------- - Models: scenario1_binary_model.h5, scenario2_multiclass_model.h5 - Figures: training_curves.png/.pdf, comparison_visualization.png/.pdf, metrics_comparison.png/.pdf - Tables: comprehensive_results.csv/.xlsx, latex_table.tex - Statistics: statistical_analysis.json, statistical_report.txt - Predictions: All test predictions and ground truth data saved PUBLICATION READINESS: ---------------------- ✓ High-resolution figures (300 DPI, PNG/PDF) ✓ LaTeX-formatted tables ✓ Comprehensive statistical analysis (Dice + IoU) ✓ Post-processing impact analysis ✓ Reproducible results with saved models ✓ Professional documentation
