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:
“Thou shalt not, it is said, make unto thee any graven image of God. The same commandment should apply when God is taken to mean the living part of every human being, the part that cannot be grasped. It is a sin that, however much it is committed against us, we almost continually commit ourselves—Except when we love.”
—Max Frisch (1911–1991)
“... the moment we try to fix our attention upon consciousness and to see what, distinctly, it is, it seems to vanish: it seems as if we had before us a mere emptiness. When we try to introspect the sensation of blue, all we can see is the blue; the other element is as if it were diaphanous. Yet it can be distinguished if we look attentively enough, and know that there is something to look for.”
—George Edward Moore (1873–1958)
