Laplacian Pyramid Toolbox

02 Feb 2006 (Updated 06 Feb 2006)

Matlab toolbox that implements the Laplacian pyramid (LP) decomposition and a new pseudo-inverse rec

File Information
Description	This toolbox contains Matlab files that implement the Laplacian pyramid (LP) decomposition [1] and the new reconstruction method in [2]. The main functions are LPD and LPR for LP decomposition and reconstruction, respectively. The script LPDEMO provides an example on how to use the main 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 2 References: [1] P.
