Computer Vision

Computer vision gives machines the ability to extract meaningful information from images and video.

Core Computer Vision Tasks

Task	Description	Example
Image Classification	Assign a label to an image	"This image contains a cat"
Object Detection	Locate and classify objects	"Car at (100,50), person at (200,300)"
Semantic Segmentation	Classify every pixel	Each pixel labelled as road, car, sky
Instance Segmentation	Distinguish individual objects	"Car 1, Car 2, Car 3"
Pose Estimation	Detect body keypoints	Skeleton overlay on a person
Image Generation	Create images from descriptions	Text-to-image, style transfer
OCR	Extract text from images	Reading documents from photographs
