## 🔧 Technical Implementation Validation

### Algorithm Choice Questions Answered:
1. **Which algorithm for detecting memory modules?**
   - ✅ **Answer: YOLOv8 Nano**
   - ✅ **Reasoning: State-of-the-art performance, real-time inference, pre-trained weights, easy integration**

2. **Hardware considerations (CPU vs GPU impact)?**
   - ✅ **Training: GPU recommended (5-10 min vs 30-60 min CPU)**
   - ✅ **Inference: CPU sufficient for real-time, GPU better for batch processing**
   - ✅ **Implementation: Auto-detection with fallback**

3. **Video input approach?**
   - ✅ **Approach described: Frame extraction + batch processing + temporal tracking**
   - ✅ **Implementation strategy provided with pseudo-code**
