Computer vision

Computer vision is an emerging technology. Here the reconstruction of explicit and meaningful descriptions of physical objects from images is carried out using some innovative techniques. Computer vision which is also known as machine vision finds applications in many areas like military, medicine and manufacturing. Computer aided tomographic scan (CT scan or CAT scan), a diagnostic tool used in medicine is based on computer vision. Computer vision finds its military application in aerial photography which helps to locate enemy naval vessels. In manufacturing field, computer vision is applied in locating and modifying different machine components such as conveyer belts, robotic mechanical parts etc. Computer vision systems are classified into three. They are two-dimensional system, stereo vision and structured light system. Two dimensional system is just like an optical comparator. Stereo vision system uses two cameras. A laser system is employed in structured light system.
