Notes
- Image filename matches its mask filename.
- For the trained models (4-class DenseNet121 classification @ 96.17% accuracy; UNet lung segmentation @ 98.71% Dice), near-duplicates were removed via MD5 + perceptual pHash (mirror-aware), leaving 19,133 unique images, split stratified 70/15/15 with no train/test leakage. See the model cards at
