Generate Gaussian or Laplacian pyramids, or reconstruct an image from a pyramid. Contains a demo script doing image blending using pyramids. The function is more convenient to use than the Matlab function impyramid.

Reconstruction yields a smaller result than the original image used to build the laplacian pyramid.
