Introduction to computer vision
Computer vision teaches machines to understand images and video.
📖 Key ideas
- Computer vision (CV) extracts meaning from images and video.
- Tasks: classification, detection, segmentation, tracking, OCR.
- Used in face unlock, self-driving cars, medical scans, retail checkout.
- Images are grids of pixels with colour channels (RGB).
- Modern CV relies on deep learning (CNNs, Vision Transformers).
💡 Real-life example: Computer vision is giving a computer eyes and a brain to understand what it sees.
