Uses the concept Pyramid (image processing) and is very similar to Gaussian Pyramid with the alteration that it uses a Laplacian transform instead of a Gaussian.
Famous quotes containing the word pyramid:
“So universal and widely related is any transcendent moral greatness, and so nearly identical with greatness everywhere and in every age,—as a pyramid contracts the nearer you approach its apex,—that, when I look over my commonplace-book of poetry, I find that the best of it is oftenest applicable, in part or wholly, to the case of Captain Brown.”
—Henry David Thoreau (1817–1862)
