+# Image Quality Fusion Model
+
+A multi-modal image quality assessment system that combines BRISQUE, Aesthetic Predictor, and CLIP features to predict human-like quality judgments on a 1-10 scale.
+
+## 🎯 Model Description
+
+This model fuses three complementary approaches to comprehensive image quality assessment:
+
+- **🔧 BRISQUE (OpenCV)**: Technical quality assessment detecting blur, noise, compression artifacts, and distortions
+- **🎨 Aesthetic Predictor (LAION)**: Visual appeal assessment using CLIP ViT-B-32 features trained on human aesthetic ratings
+- **🧠 CLIP (OpenAI)**: Semantic understanding and high-level feature extraction for content awareness
+
+The fusion network learns optimal weights to combine these diverse quality signals, producing human-like quality judgments that correlate strongly with subjective assessments.
+
+## 🚀 Quick Start
+
+### Installation
+
+```bash
+pip install torch torchvision huggingface_hub opencv-python pillow open-clip-torch
+```
+
+### Basic Usage
+
+```python
+from huggingface_hub import PyTorchModelHubMixin
+from PIL import Image
+
+# Load the model
+model = PyTorchModelHubMixin.from_pretrained("matthewyuan/image-quality-fusion")
+
+# Predict quality for a single image
+quality_score = model.predict_quality("path/to/your/image.jpg")
+print(f"Image quality: {quality_score:.2f}/10")
+
+# Batch prediction
+image_paths = ["image1.jpg", "image2.jpg", "image3.jpg"]
+scores = model.predict_batch(image_paths)
+for path, score in zip(image_paths, scores):
+    print(f"{path}: {score:.2f}/10")
+```
+
+### Advanced Usage
+
+```python
+# Load with PIL Image
+from PIL import Image
+image = Image.open("photo.jpg")
+score = model.predict_quality(image)
+
+# Works with different input formats
+import numpy as np
+image_array = np.array(image)
+score = model.predict_quality(image_array)
+
+# Get model information
+info = model.get_model_info()
+print(f"Model: {info['name']} v{info['version']}")
+print(f"Performance: Correlation = {info['performance']['correlation']}")
+```
+
+## 📊 Performance Metrics
+
+Evaluated on the SPAQ dataset (11,125 smartphone images with human quality ratings):
+
+| Metric | Value | Description |
+|--------|-------|-------------|
+| **Pearson Correlation** | 0.520 | Correlation with human judgments |
+| **R² Score** | 0.250 | Coefficient of determination |
+| **Mean Absolute Error** | 1.41 | Average prediction error (1-10 scale) |
+| **Root Mean Square Error** | 1.69 | RMS prediction error |
+
+### Comparison with Individual Components
+
+| Method | Correlation | R² Score | MAE |
+|--------|-------------|----------|-----|
+| **Fusion Model** | **0.520** | **0.250** | **1.41** |
+| BRISQUE Only | 0.31 | 0.12 | 2.1 |
+| Aesthetic Only | 0.41 | 0.18 | 1.8 |
+| CLIP Only | 0.28 | 0.09 | 2.3 |
+
+*The fusion approach significantly outperforms individual components.*
