In image processing, computer vision and related fields, an image moment is a certain particular weighted average (moment) of the image pixels' intensities, or a function of such moments, usually chosen to have some attractive property or interpretation.
Image moments are useful to describe objects after segmentation. Simple properties of the image which are found via image moments include area (or total intensity), its centroid, and information about its orientation.

Famous quotes containing the words image and/or moment:
“I think that cars today are almost the exact equivalent of the great Gothic cathedrals: I mean the supreme creation of an era, conceived with passion by unknown artists, and consumed in image if not in usage by a whole population which appropriates them as a purely magical object.”
—Roland Barthes (1915–1980)
“How truly does this journal contain my real and undisguised thoughts—I always write it according to the humour I am in, and if a stranger was to think it worth reading, how capricious—insolent & whimsical I must appear!—one moment flighty and half mad,—the next sad and melancholy. No matter! Its truth and simplicity are its sole recommendations.”
—Frances Burney (1752–1840)
