Image analysis is the extraction of meaningful information from images; mainly from digital images by means of digital image processing techniques. Image analysis tasks can be as simple as reading bar coded tags or as sophisticated as identifying a person from their face. In common usage, an image (from Latin imago) or picture is an artifact that reproduces the likeness of some subject—usually a physical object or a person. ... A digital image is a representation of a two-dimensional image as a finite set of digital values, called picture elements or pixels. ... Digital image processing is the use of computer algorithms to perform image processing on digital images. ... This article or section does not cite its references or sources. ... A facial recognition system is a computer-driven application for automatically identifying a person from a digital image. ...


Computers are indispensable for the analysis of large amounts of data, for tasks that require complex computation, or for the extraction of quantitative information. On the other hand, the human visual cortex is an excellent image analysis apparatus, especially for extracting higher-level information, and for many applications — including medicine, security, and remote sensing — human analysts still cannot be replaced by computers. For this reason, many important image analysis tools such as edge detectors and neural networks are inspired by human visual perception models. A BlueGene supercomputer cabinet. ... Brodmann area 17 (primary visual cortex) is shown in red in this image which also shows area 18 (orange) and 19 (yellow) The visual cortex refers to the primary visual cortex (also known as striate cortex or V1) and extrastriate visual cortical areas such as V2, V3, V4, and V5. ... The goal of edge detection is to mark the points in a digital image at which the luminous intensity changes sharply. ... A neural network is an interconnected group of neurons. ...

Computer image analysis

Computer image analysis largely contains the fields of computer or machine vision, and medical imaging, and makes heavy use of pattern recognition, digital geometry, and signal processing. This field of computer science developed in the 1950s at academic institutions such as the MIT A.I. Lab, originally as a branch of artificial intelligence and robotics. To meet Wikipedias quality standards, this article or section may require cleanup. ... Machine vision (MV) is the application of computer vision to industry and manufacturing. ... Medical imaging designates the ensemble of techniques and processes used to create images of the human body (or parts thereof) for clinical purposes (medical procedures seeking to reveal, diagnose or examine disease) or medical science (including the study of normal anatomy and function). ... Pattern recognition is a field within the area of machine learning. ... Digital geometry deals with discrete sets (usually discrete point sets) considered to be digitized models or images of objects of the 2D or 3D Euclidean space. ... Signal processing is the processing, amplification and interpretation of signals, and deals with the analysis and manipulation of signals. ... Computer science, or computing science, is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. ... The Massachusetts Institute of Technology (MIT) is a private, coeducational research university located in Cambridge, Massachusetts. ... Hondas humanoid robot AI redirects here. ... It has been suggested that this article or section be merged with robot. ...


It is the quantitative or qualitative characterization of two-dimensional (2D) or three-dimensional (3D) digital images. 2D images are, for example, to be analyzed in computer vision, and 3D images in medical imaging. The field was established in the 1950s -- 1970s, for example with pioneering contributions by Azriel Rosenfeld, Herbert Freeman, Jack E. Bresenham, or King-Sun Fu. A scale for measuring mass A quantitative property is one that exists in a range of magnitudes, and can therefore be measured. ... Qualitative is an important qualifier in the following subject titles: Qualitative identity Qualitative marketing research Qualitative method Qualitative research THE BIG J This is a disambiguation page — a list of pages that otherwise might share the same title. ... Dimension (from Latin measured out) is, in essence, the number of degrees of freedom available for movement in a space. ... The space we live in is three-dimensional space. ... A digital image is a representation of a two-dimensional image as a finite set of digital values, called picture elements or pixels. ...

Medical imaging designates the ensemble of techniques and processes used to create images of the human body (or parts thereof) for clinical purposes (medical procedures seeking to reveal, diagnose or examine disease) or medical science (including the study of normal anatomy and function). ... Professor Dr. Azriel Rosenfeld (February 19, 1931 - February 22, 2004) was Research Professor, a Distinguished University Professor, and Director of the Center for Automation Research at the University of Maryland in College Park, Maryland, where he also held affiliate professorships in the Departments of Computer Science, Electrical Engineering, and Psychology. ... Dr. Herbert Freeman is a computer scientist who made important contributions to the field of computer graphics, including anti-aliasing and machine vision. ... Jack E. Bresenham is a professor of computer science. ... Dr. King-Sun Fu (died April 29, 1985) was a professor at Purdue University in West Lafayette, Indiana. ...


Digital image analysis

The applications of digital image analysis are continuously expanding through all areas of science and industry, including:

Each of these application areas has spawned separate subfields of digital image analysis, with a large collection of specialized algorithms and concepts -- and with their own journals, conferences, technical societies, and so on. Medical imaging is the process by which physicians evaluate an area of the subjects body that is not normally visible. ... Microscope image processing is a broad term that covers the use of digital image processing techniques to process, analyze and present images obtained from a microscope. ... Synthetic aperture radar image of Death Valley colored using polarimetry In the broadest sense, remote sensing is the measurement or acquisition of information of an object or phenomenon, by a recording device that is not in physical or intimate contact with the object. ... Astrophotography is a specialized type of photography that entails making photographs of astronomical objects in the sky such as the Moon, Sun, planets, stars, and deep sky objects such as star clusters and galaxies. ... In military science, defense (or defence) is the art of preventing an enemy from conquering territory. ... The Materials Science Tetrahedron, which often also includes Characterization at the center Materials science is an interdisciplinary field involving the properties of matter and its applications to various areas of science and engineering. ... Machine vision (MV) is the application of computer vision to industry and manufacturing. ... To meet Wikipedias quality standards, this article or section may require cleanup. ... It has been suggested that this article or section be merged with robot. ... Optical character recognition, usually abbreviated to OCR, is a type of computer software designed to translate images of handwritten or typewritten text (usually captured by a scanner) into machine-editable text, or to translate pictures of characters into a standard encoding scheme representing them (e. ... Plate readers (also know as microplate readers) are laboratory instruments designed to detect biological, chemical or physical events in samples stored in microtiter plates. ...
