What is computer vision?:

What is computer vision? It is the science and technology of machines that means the machine is able to extract information from an image, to solve some task. computer vision is concerned with the theory behind artificial systems that extract information from images. The image data can take many forms, such as video sequences, views from multiple cameras, or multi-dimensional data from a medical scanner.

.:

. Sub-domains of computer vision include scene reconstruction, event detection, video tracking , object recognition , learning, indexing, motion estimation , and image restoration . Computer vision is closely related to the study of biological vision. Computer vision is, in some way inverse of Computer Graphics.

State of the art:

State of the art Computer vision is a diverse and relatively new field of study. Computer vision is cover wide range of topics which are often related to other disciplines and consequently there is no standard formula to solve any problem.

Related fields :

Related fields Artificial intelligence and computer vision share topics such as Pattern Recognition and Learning techniques. Physics is another field that is closely related to computer vision. A third field which plays an important role is neurobiology , specifically the study of the biological vision system.

Conutinue…. :

Conutinue …. Yet another field related to computer vision is signal processing . The fields most closely related to computer vision are image processing , image analysis and machine vision . There is a significant overlap in the range of techniques and applications that these cover.

Applications for computer vision :

Applications for computer vision Computer vision is mostly used in Medical field. Generally, image data is in the form of microscopy images , X-ray images , angiography images , ultrasonic images , and tomography images . It can also be measurements of organ dimensions, blood flow, etc. This application area also supports medical research by providing new information, e.g., about the structure of the brain, or about the quality of medical treatments.

.:

. A second application area in computer vision is in industry, sometimes called machine vision , where information is extracted for the purpose of supporting a manufacturing process. One example is quality control where details or final products are being automatically inspected in order to find defects. Machine vision is also heavily used in agricultural process to remove undesirable food stuff from bulk material, a process called optical sorting .

.:

. Military applications are probably one of the largest areas for computer vision. The obvious examples are detection of enemy soldiers or vehicles and missile guidance

Typical tasks of computer vision:

Typical tasks of computer vision Recognition The classical problem in computer vision, image processing, and machine vision is that of determining whether or not the image data contains some specific object, feature, or activity. Scene reconstruction Given one or (typically) more images of a scene, or a video, scene reconstruction aims at computing a 3D model of the scene. In the simplest case the model can be a set of 3D points. More sophisticated methods produce a complete 3D surface model.

.:

. Image restoration The aim of image restoration is the removal of noise (sensor noise, motion blur, etc.) from images. The simplest possible approach for noise removal is various types of filters such as low-pass filters or median filters.

Conclusion:

Conclusion Computer vision is a machine that can be extract information from the image. Computer vision is closely related to the study of Biological vision. Computer vision is the inverse of Computer graphics in some way.

.:

. Computer vision is cover wide range of topic which are related to other disciplines. Computer vision is related to other various fields.
