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
