Skin Lesion Identification Based on Dermoscopic Images

https://github.com/madriss/Dermoscopy-CNN
This Python-based app loads a fine-tuned EfficientNet model trained to identify various skin lesions from dermoscopic images. The model can identify melanomas, melanocytic nevus, basal cell carcinoma, actinic keratosis, Bowen’s disease, different types of benign keratosis, dermatofibroma, and vascular lesions.

Breast Cancer Detection Using Histological Slices

https://github.com/madriss/Breast_Cancer_Detection-Histopathology
This Python and Flask-based app classifies slices to detect breast cancer tissues vs. normal tissues. The app loads a fine-tuned EfficientNet model and implements Grad-CAM heatmaps to display the most relevant zones in the slice according to the model. The app was built using a Dockerfile and deployed on Google Cloud Platform (GCP).

French IBAN Retriever Using OCR

https://github.com/madriss/ocr_demo
This small Python-based optical character recognition (OCR) project uses the Tesseract API to extract French IBANs from scanned photos. The app was built using the Streamlit framework and deployed on GCP.
