{{disambig}} '''Imagery''' is a collective term for pictorial information that can be transmitted electronically. It includes still pictures (e.g., [[facsimile]]) as well as sequences of individual images that simulate motion (e.g., [[television]]). Imagery need not be what the human eye would perceive. It includes the output of [[night vision devices]], "false color" systems that transpose particular [[infrared]] wavelengths into human-visible colors, etc. Both medical and military imaging share the challenge of combining image data taken with different resolutions, [[spatial orientation]]s, [[time bases]], and [[coordinate systems]]. For efficiency in transmission, they may be compressed with techniques such as [[JPEG]] for still images and [[MPEG-1]] for moving pictures. ''Specifically,'' '''imagery''' ''may refer to:'' {{r|guided imagery}} {{r|diagnostic imaging}} {{r|imagery (computer graphics)}} {{r|imagery intelligence}} {{r|imagery (psychotherapy)}}
