How to create multi-level wavelet transform?

    The ippsWTFwd creates one level of wavelet. 
ippsWTFwd_32f( pSrc, pLow, pHigh, 6, pFwdState );

If i want to create another level of wavelet, shall i set pLow as input?

Such as:

ippsWTFwd_32f( pLow, pLow2, pHigh2, 6, pFwdState2 );

And shall i create another pFwdState2 as it is said in other topics?

So the forward and inverse wavelet transform is iterative？

Hi Lu,

Hi Lu,

Sorry to reply late! Yes, the multi level transform should be set as you describe.
