Abstract

Computer vision is the process of using computers to extract from images useful information about the physical world, including meaningful descriptions of physical objects. For example, if an image sensor, such as a digitizing video camera, captured an image of a physical scene, and the digital image was input to a computer vision system, the desired output would be a description of the physical scene in terms that would be useful for the particular task at hand. Computer vision has many applications, including robotics, industrial automation, document processing, remote sensing, navigation, microscopy, medical imaging, and the development of visual prostheses for the blind.
