## Definition
Computer Vision is a field of artificial intelligence that trains computers to interpret and understand the visual world. Using digital images from cameras and videos, models can accurately identify and classify objects, and react to what they "see."

## Architectural Mechanics & Deep Dive
Computer Vision is a subfield of artificial intelligence that enables computers and systems to derive meaningful information from digital images, videos, and other visual inputs. Using deep learning models, particularly CNNs and Vision Transformers (ViTs), computer vision systems can perform tasks like image classification, object detection, facial recognition, image segmentation, and autonomous navigation for self-driving vehicles.

## Industry Applications & Real-World Use Cases
Autonomous driving, medical scan analysis, manufacturing inspections, and facial recognition.

## Frequently Asked Questions

### What are the main tasks in computer vision?
Image classification (identifying what's in an image), Object detection (locating objects), and Image segmentation (pixel-level tracing).

### How has deep learning impacted computer vision?
It replaced hand-crafted visual feature filters with deep CNNs and Vision Transformers that learn features automatically from pixel datasets.
