Gaussian_pyramid

The project is a small example of Gaussian pyramid and Luplcian pyramid without openCV.

There are few steps to create a gaussian pyramid

  1. Weighted down using a Gaussian blur
  2. Scale down with the length and width to 1/2.
  3. repeat the 1&2 steps to make next layer of pyramid.

The result would like that Alt text

To make a Luplacian pyramid needs

  1. Scale the layer up with the length and width to 2
  2. The previous Gaussian pyramid layer minus the scaled-up layer.
  3. repeat the 1&2 steps to make next layer of pyramid.

The result would like that ![Alt text] (https://github.com/night18/Gaussian_pyramid/blob/master/Laplacian.png "Luplacian pyramid")
