1. Define Computer Vision

Explain that computer vision is a field of AI that enables computers to extract, analyze, and understand information from digital images or videos.

2. Describe the Core Pipeline

Outline the typical pipeline: image acquisition, preprocessing (e.g., noise reduction, normalization), feature extraction, and high-level interpretation.

3. Highlight Key Tasks

Mention fundamental tasks such as image classification, object detection, semantic segmentation, and instance segmentation, with examples.

4. Discuss Deep Learning Impact

Explain how deep learning, particularly CNNs, has become the dominant approach, enabling end-to-end learning and surpassing traditional handcrafted features.

5. Relate to Autonomous Driving

Connect these fundamentals to autonomous driving applications, such as perception, sensor fusion (camera, LiDAR, radar), and real-time inference challenges.

Key Points to Mention

  • Image formation and sensing (cameras, LiDAR, etc.)
  • Preprocessing techniques (filtering, normalization, augmentation)
  • Feature extraction: from handcrafted (SIFT, HOG) to learned (CNN features)
  • Core tasks: classification, detection, segmentation, tracking
  • Deep learning architectures: CNNs, transformers, and their trade-offs
  • Evaluation metrics: accuracy, IoU, mAP, and real-time constraints
