Computer vision is the part of AI that analyses images and video, for example to recognise objects, text or faces.
Example
An app recognises a plant in a photo and tells you its name.
For pros
Tasks include classification, object detection, segmentation and text recognition (OCR). Today multimodal models process images and text together. Face recognition is legally sensitive: biometric data has special protection under the GDPR, and the EU AI Act prohibits certain uses.
