ImagePyramid for Multiscale Image Representation

ImagePyramid can create a multi-resolution representation of an image to facilitate efficient multiscale processing. Typical image pyramids are Gaussian and Laplacian pyramids.

Gaussian pyramid is a sequence of images blurred using the Gaussian kernel and downsampled.

Laplacian pyramid is similar to the Gaussian pyramid, but saves the difference between original and blurred images at each level except for the smallest image. Saving the original at the last level allows for reconstruction at higher resolutions.

Reconstruct the image from the Laplacian pyramid.
