+- **InsightFace**: 0.7.3 (Face detection)
+- **XFormers**: 0.0.28.post1 (Memory-efficient attention)
+
+### AI Pipeline
+1. **Face Detection**: InsightFace Buffalo_L
+2. **Enhancement**: Stable Diffusion v1.5 with DPM++ scheduler
+3. **Blending**: Poisson seamless cloning or alpha blending
+4. **Optimization**: GPU acceleration with memory management
+
+## 🚀 Usage
+
+### Image Processing
+1. Upload target image and reference face
+2. Adjust enhancement prompt and settings
+3. Select blend method (Poisson recommended)
+4. Process with AI optimizations
+
+### Video Processing
+1. Upload video (up to 120 frames supported)
+2. Provide reference face image
+3. Configure processing parameters
+4. Generate enhanced video
+
+## ⚙️ Advanced Settings
+
+- **Transformation Strength**: 0.2-1.0 (higher = more dramatic)
+- **Guidance Scale**: 1.0-20.0 (higher = stronger prompt following)
+- **Quality Steps**: 15-50 (more steps = better quality)
+- **Blend Method**: Poisson (seamless) or Alpha (soft)
+
+## 💡 Tips for Best Results
+
+1. **High-Quality Images**: Use well-lit, high-resolution photos
+2. **Clear Face Visibility**: Front-facing angles work best
+3. **Prompt Engineering**: Detailed prompts improve results
+4. **Poisson Blending**: Use for seamless integration
+
+## 🎯 Recommended Hardware
+
+- **CPU**: 8+ cores, 16GB+ RAM
