+## 📚 Project Overview
+
+Style transfer is a technique in deep learning that involves using Convolutional Neural Networks (CNNs) to separate and combine the style of one image with the content of another image. This project implements a neural style transfer model using **PyTorch** and **pre-trained VGG19**.
+
+### Key Features:
+- Use of **pre-trained neural networks** for feature extraction (VGG19)
+- Content loss and style loss based on **Gram matrices**
+- Supports custom content and style images
+- Optimization with **L-BFGS** optimizer for faster convergence
+
+## 🛠️ Setup & Installation
+
+To get started with this project, you'll need to install the following dependencies:
+
+```bash
+pip install torch torchvision matplotlib Pillow
+```

+## 🚀 How to Run
+1. Clone the repository and navigate to the project folder:
+    ```bash
+    git clone https://github.com/yourusername/style-transfer-project.git
+    cd style-transfer-project
+    ```
+
+2. Run the Jupyter Notebook to perform style transfer on your images. You can upload your custom content and style images in the notebook.
+
+3. Adjust parameters like `content_weight`, `style_weight`, and `num_steps` for different results.
+
+4. View and save the generated images in the `output/` folder.
+
+## 📸 Sample Run
+
+- **Content Image**: Defines the structure and objects in the final image.
+- **Style Image**: The textures, colors, and patterns are provided.
+
+| Content Image                                                                                  | Style Image                                                                                   |

+
+## 🔬 Concepts Behind the Project
+- **Content Representation**: Extracted from deeper layers of the neural network to capture the high-level structures in the image.
+- **Style Representation**: Captured using the Gram matrix of feature maps, representing the correlations between different feature maps.
+- **Optimization**: The neural network optimizes a random noise image to minimize content and style loss, blending the content and style.
+
+## 🧠 Technologies Used
+- Python 🐍
+- PyTorch for deep learning
+- Jupyter Notebook for interactive coding
+- Matplotlib for visualizations
+
+## 📊 Parameters & Tuning
+You can adjust the following parameters to control the output:
+
+| Parameter       | Default Value | Description                      |
+|------------------|---------------|----------------------------------|
+| `content_weight` | 1e5          | Weight for the content loss      |
+| `style_weight`   | 1e10         | Weight for the style loss        |
+| `num_steps`      | 300          | Number of optimization steps      |
+| `learning_rate`  | 0.01         | Learning rate for the optimizer   |
