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
These goals are achieved by means of pattern recognition
, statistical learning
, projective geometry
, image processing
, graph theory
and other fields. Cognitive computer vision is strongly related to cognitive psychology
and biological computation.
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.
