'''Cognition Network Technology''' is an [[object-based image analysis]] method developed by Nobel prize winner [[Gerd Binnig]] together with a team of researchers at Definiens AG in Munich, Germany.
First launched in May 2000, '''eCognition''' introduced the computer method for extracting information from images using a hierarchy of image objects (groups of pixels) as opposed to traditional pixel processing methods. The technology, referred to as Cognition Network Technology, was realized by [[Gerd Binnig]] together with a team of researchers at Definiens AG in Munich, Germany. In June 2010, Trimble Navigation Ltd (NASDAQ: TRMB) acquired Definiens business assets<ref>Trimble / Definiens Joint Press Release: "Trimble Acquires Definiens’ Earth Sciences Business to Expand its GeoSpatial Portfolio". June 11, 2010. http://www.ecognition.com/sites/default/files/Trimble%20eCognition.pdf</ref> in earth sciences markets including eCognition software.▼
It serves for extracting information from images using a hierarchy of image objects (groups of pixels), as opposed to traditional pixel processing methods.
To emulate the human mind's cognitive powers, Definiens used patented [[image segmentation]] and classification processes, and developed a method to render knowledge in a semantic network. The technology examines pixels not in isolation, but in context. It builds up a picture iteratively, recognizing groups of pixels as objects. It uses the color, shape, texture and size of objects as well as their context and relationships to draw conclusions and inferences, similar to a human analyst.
It was first available with the launch of the ''eCognition'' software in May 2000.

== Software ==
The eCognition Suite offers three components which can be used stand-alone or in combination to solve image analysis tasks. eCognition Developer is a development environment for object-based image analysis. It is used in earth sciences to develop rule sets (or applications) for the analysis of remote sensing data. eCognition Architect enables non-technical users to configure, calibrate and execute image analysis workflows created in eCognition Developer. eCognition Server software provides a processing environment for batch execution of image analysis jobs.
== Industrial Applications ==
eCognition software is utilized in numerous [[remote sensing]] and geospatial application scenarios and environments, using a variety of data types.
