Gaussian Pyramid

A Gaussian pyramid is a set of images that are successively blured and subsampled repeatedly. The recursive operation is applied on each step so many levels can be created. Gaussian Pyramids have many computer vision applications, and are used in many places.

Basic Description

Gaussian pyramids are formed by a recursive operation on the top level of the pyramid. From any given level k of the pyramid, one can generate the next level, k+1, by convolving level k with a Gaussian blur kernel and then subsampling it. Because of this, each new level generated will be smaller than the previous, hence the name Gaussian pyramid.
