'''Cognition Network Technology''' (CNT) is an [[object-based image analysis]] method developed by Nobel laureate [[Gerd Binnig]] together with a team of researchers at Definiens AG in Munich, Germany.

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 technologyCNT 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.

In June 2010, [[Trimble Navigation Ltd]] (NASDAQ: TRMB) acquired Definiens business asset in [[earth businesssciences]] assetsmarkets,<ref>Trimble / Definiens Joint Press Release: "Trimble Acquires Definiens’ Earth Sciences Business to Expand its GeoSpatial Portfolio".
