MATLAB Software for Video Denoising using 3D Wavelet Packets
------------------------------------------------------------

Although the Wavelet Packet Denoising Package is extended from the 
WaveLab, it is self-contained and does not require the WaveLab 
distribution to run.  But you probably need to get one if you are NOT 
using Linux.  Just need to replace

DownDyadHi.mexglx
DownDyadLo.mexglx
UpDyadHi.mexglx
UpDyadLo.mexglx

with .m files:

DownDyadHi.m
DownDyadLo.m
UpDyadHi.m
UpDyadLo.m

The major routines in the package are documented below:

bayesThreshold.m    Performs the BayesThresholding on the coefficents.
bayesThreshold1.m   Performs the same thresholding but with proposed sigma 
                    estimates.
estimateNoise.m     Does the proposed noise sigma estimation.

denoise_wp_bayes.m  The routine takes a noisy image, does the forward 
                    Wavlet Packet transform, perform the thresholding 
                    and inverse it back.

psnr.m              PSNR metric on data.


All listed *.m files are with help comments.
