Laplacian Pyramid Toolbox (version 1.0, June 2004)http://www.ifp.uiuc.edu/~minhdo/software/This toolbox contains Matlab files that implement the Laplacian pyramid (LP) decomposition and the new reconstruction method in [1].The main functions are LPD and LPR for LP decomposition and reconstruction,respectively.  The script LPDEMO provides an example on how to use themain functions in the toolbox.Features:+ Can handle signals of any dimension+ Contain several popular pyramid filters such as '9/7', '5/3' and the   original 'Burt' filters+ Have border handling Limitation:- Only work with signal size of power of 2References:[1] M.
