2D Wavelet - how to find correct anchor values?

2D Wavelet - how to find correct anchor values?

I'm trying to use the 2d wavelet functions with the bior4.4 wavelet (from Matlab, values available at

In Matlab, I can get perfect reconstrution using a simple test matrix, but I get non-sensical values with IPP. I think that's due to having wrong anchor values: I'm using 0 for every anchor.

How can I deduce the correct anchor values?

Hi Thomas,

You may refer tothe 2d wavelet sample in IPP \ipp-samples\image-processing

Hi Ying,

the 2d wavelet sample deals only with the Daubechie, order2 wavelet. I don't quite see how I can continue from this sample.
