ECognition
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〔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〕 in earth sciences markets including eCognition software.
== Cognition Network Technology ==
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.
