Humans use their eyes and their brains to see and visually sense the world around them. Computer vision is the science that aims to give a similar, if not better, capability to a machine or computer.

Computer vision is concerned with the automatic extraction, analysis and understanding of useful information from a single image or a sequence of images. It involves the development of a theoretical and algorithmic basis to achieve automatic visual understanding.

The applications of computer vision are numerous and include:

• agriculture
• augmented reality
• autonomous vehicles
• biometrics
• character recognition
• forensics
• industrial quality inspection
• face recognition
• gesture analysis
• geoscience
• image restoration
• medical image analysis
• pollution monitoring
• process control
• remote sensing
• robotics
• security and surveillance
• transport
