+# Celebrity Face Recognition
+
+This project involves training a machine learning model to recognize images of five celebrities: Madonna, Mindy Kaling, Jerry Seinfeld, Elton John, and Ben Affleck. The model is trained on a dataset containing images of these celebrities and is capable of predicting the celebrity in new images with a reasonable degree of accuracy.
+
+## DataSet Preparation
+The dataset used in this project is a collection of images of the five celebrities mentioned above. Download images from https://www.kaggle.com/datasets/dansbecker/5-celebrity-faces-dataset.
+
+## Project Structure
+
+- `train`: Directory containing training images of the celebrities.
+- `val`: Directory containing validation images of the celebrities.
+- `celebrity_recognition_model.h5`: The trained Keras model.
+- `label_encoder.pkl`: The label encoder used for transforming class labels.
+
+## Dependencies
+
+The project requires the following Python packages:
+
+- `tensorflow`
+- `numpy`
+- `opencv-python`
+- `matplotlib`
+- `scikit-learn`
+
+These can be installed using the provided `requirements.txt` file.
+
+## Usage
+
+### Training the Model
+
+1. Place the training images in the `train` directory with each celebrity's images in their respective folders.
+2. Preprocess the images using data generators and train a convolutional neural network (CNN) model.
+3. Save the trained model and the label encoder for future use.
+
+### Predicting on Validation Data
+
+1. Load the trained model and label encoder.
+2. Use the validation data to test the model's performance.
+3. Display the predictions for the validation images, showing the predicted celebrity names.
+
+## Example Workflow
+
+1. **Prepare the Dataset**: Organize the images into `train` and `val` directories with subdirectories for each celebrity.
+2. **Train the Model**: Use a CNN to learn features from the training images and save the model.
+3. **Validate the Model**: Load the model and evaluate it on the validation set to check its performance.
+4. **Display Predictions**: Visualize the predictions by displaying validation images with the predicted celebrity labels.
+
+## Requirements
+
+- TensorFlow
+- NumPy
+- OpenCV
+- Matplotlib
+- Scikit-learn
