Computer Vision is a subfield of Artificial intelligence. The purpose of computer vision is to program a computer to "understand" a scene or features in an image.
Typical goals of computer vision include:
- The detection, segmentation, location, and recognition of certain objects in images (e.g., human faces)
- Registration of different views of the same scene or object
- Tracking an object through an image sequence
- Mapping a scene to a three-dimensional model of the scene; such a model might be used by a robot to navigate the imaged scene
- Estimation of the three-dimensional poses of humans and their limbs
In the related fields machine vision and medical imaging, systems using computer vision techniques are sold in markets worth billions of US dollars per year.
