Concept Reminders

Artificial Intelligence

Artificial Intelligence (AI) is a field of computing that develops systems capable of performing tasks that normally require aspects of human intelligence, such as learning, reasoning, perception and decision-making.

Computer Vision

Computer Vision is a field of AI that enables computers to process and interpret visual information such as images and videos.

Common Computer Vision Tasks

  • Image classification
  • Object detection
  • Face detection and recognition
  • Image segmentation
  • Optical character recognition (OCR)
  • Motion and activity analysis

Examples of Computer Vision Applications

Field Example Application Purpose
Healthcare Medical image analysis Helps analyse medical images for clinical decision support.
Transportation Traffic monitoring Detects vehicles, traffic conditions and road events.
Security Face or object detection Helps identify or track relevant visual information.
Retail Product recognition Helps analyse products, shelves and customer activity.
Agriculture Crop monitoring Helps detect crop conditions, weeds or visible plant problems.
Education Document and handwriting analysis Can assist with recognising text and visual content.
