⚙️ Under the hood
CNN (Convolutional Neural Network)
CNNs, CNN
A neural network for images: small filters slide across the picture, detecting edges first, then shapes, then whole objects.
💭 Imagine …
Like moving a magnifying glass across a photo: lines first, then corners, then “an eye”, then “a face”.
🔎 Example
Quality control in manufacturing, document recognition, medical imaging. Today partly complemented by vision transformers.
🎯 Why it matters
CNNs brought the image-recognition breakthrough from 2012 and still run in many systems.
