(The Wikipedia page name is "Pyramid (image processing)", but this page uses the more commonly used term, the OpenCV page name)
Pyramid, or pyramid representation, is a type of multi-scale signal representation developed by the computer vision, image processing and signal processing communities, in which a signal or an image is subject to repeated smoothing and subsampling. Pyramid representation is a predecessor to scale-space representation and multiresolution analysis.
