TL;DR

Computer vision datasets are curated collections of labeled images and videos (training data) used to teach AI models. They support tasks like object detection, segmentation, and classification using benchmarks like the COCO dataset or ImageNet. Data quality, dataset diversity, and accurate data annotation are critical, as data bias in these massive datasets directly limits model performance.

We use computer vision (CV) every day. It helps us unlock our phones through facial recognition and guides self-driving cars as they navigate.

All these systems first learn to see through vast collections of labeled dataset images and videos, referred to as computer vision datasets.

It provides machines with visual information and teaches them to interpret it.
