+# Cataract Disease Detection using Machine Learning
+
+
+## Model Training and evaluation :
+
+CNN model is trained over batch size = 32 , input image size =(224,224) over 20 epocchs and achieved average validation accuracy of 87.5 %.
+
+## Dataset :
+
+https://www.kaggle.com/datasets/akshayramakrishnan28/cataract-classification-dataset/data
+
+
+## Inference : 
+
+Deployed the model with the help streamlit web application to predict the possibility of eye  cataract , cataract disease symptoms , risks , statistics , grpahs and nearby eye clinic search.
+
+## Libraries Used
+
+1. **Joblib**: For downloading the random forest model
+2. **Scikit learn**: For machine learning processing  and operations
+3. **Matplotlib**: For plotting and visualizing the detection results.
+4. **Pandas**: For image manipulation.
+5. **NumPy**: For efficient numerical operations.
+6. **Seaborn** : for advanced data visualizations
+7. **plotly** : for 3D data visualizations .
+8. **Streamlit** : for creating gui of the web application.
+9. **Tensorflow** : for image based manipulation operations.
+
+
+## How to Use
+
+1. **Clone the Repository**: 
+    ```sh
+    git clone url_to_this_repository
+    ```
+
+2. **Install Dependencies**: 
+    ```sh
+    pip install -r requirements.txt
+    ```
+
+3. **Run the Model**: 
+    (download the model cataract_detection_model.h5 from below link and put in same directoy :
+      https://drive.google.com/file/d/17Um-KcGOBz8G3s6s4nJj1lJ-C8BPT8rN/view?usp=sharing)
+
+    ```python
+    streamlit run app.py
+    ```
+
+4. **View Results**: The script will allow you to predict the possbility of cataract.
+
+**DEMO** :
