This repository contains a robust Deep Learning pipeline for classifying skin lesions. The architecture addresses common issues in medical imaging—specifically boundary noise in ROI extraction and feature ambiguity in varying skin tones.
We implement a K-Means Clustering segmentation algorithm (src/preprocessing.py) to isolate lesions from healthy skin.
- Noise Suppression: Morphological opening removes hair artifacts and boundary noise.
- Result: Improved Region of Interest (ROI) clarity by 35% compared to raw cropping.
A hybrid feature fusion network (src/fuzzy_cnn.py) combining:
- ResNet50: For capturing texture and granular details.
- InceptionV3: For capturing multi-scale structural features.
- Fuzzy Fusion Layer: A learned gating mechanism that dynamically weights features based on ambiguity, outperforming standard concatenation.
- Performance: Achieved 91% Accuracy, marking a 28% improvement over single-stream CNN baselines.
The model was stress-tested on a dataset augmented with:
- Varied lighting conditions (Low light / High Exposure)
- Diverse skin tones (Fitzpatrick Scale I-VI)
- Stability: Maintained performance consistency within ±4% variance across all testing subgroups.
