+## Models used 
+
+- logistic regression
+- Random Forest
+- SVM
+- GBM
+
+## Libraries Used
+
+1. **joblib**: To dowload and laod the model
+2. **plotly**: For plotting zooming and 3d visualizations
+3. **Matplotlib**: For plotting and visualizing the detection results.
+4. **Pandas**: For image manipulation.
+5. **NumPy**: For efficient numerical operations.
+6. **Streamlit** : for building web app gui.
