Abstract
Computer vision is the science of endowing computers or other machines with vision, or the ability to see. The ultimate goal of computer vision is to model and replicate human vision using computer software and hardware at differentlevels .It combines knowledge in computer science ,electrical engineering ,mathematics , physiology , biology , and cognitive science . It needs knowledge from all these fields in order to understand and simulate the operation of the human vision system.The objective of studying computer vision is segmentation, reconstruction the 3D world, recognition and control. Related topics: image processing, computer graphics, pattern recognition, perception , robotics and AI. Some Applications for computer vision are medical computer vision or medical image processing,machine vision, Military applications, autonomous vehicles. There are many Typical tasks of computer vision such as Recognition,Motion analysis , Scene reconstruction , Image restoration.The organization of a computer vision system is highly application dependent. Some systems are stand-alone applications which solve a specific measurement or detection problem, while others constitute a sub-system of a larger design which, for example, also contains sub-systems for control of mechanical actuators, planning, information databases, man-machine interfaces, etc. Typical functions which are found in many computer vision systems are Image acquisition,pre-processing, feature extraction, direction/segmentation, high level processing , decision making.There are manykind of computer vision systems, nevertheless all of them contains these basic elements: power source, at least one image acquisition device (i.e. camera, ccd, etc), processor as well as control and communication cables or some kind of wireless interconnection mechanism. In addition a practicalvision system contains software for application and develop as well as display in order to monitor what the system does. Vision system for inner spaces, as most industrial ones, contains in addition an illumination system and in most cases a controlled environment, specially on external lighting. Furthermore, a completed system includes many accessories like camera supports, cables and connectors.
