In image processing, phase correlation is a method of image registration, and uses a fast frequency-domain approach to estimate the relative translative offset between two similar images.
Famous quotes containing the word phase:
“The problem of the twentieth century is the problem of the color-linethe relation of the darker to the lighter races of men in Asia and Africa, in America and the islands of the sea. It was a phase of this problem that caused the Civil War.”
—W.E.B. (William Edward Burghardt)
