Second Stage Filters

Calling Sequence

[af,sf]=dualfilt1('f')
af=dualfilt1('a')
sf=dualfilt1('s')

Parameters

c :: flag, 'f' for full, 'a' for analysis and 's' for synthesis
af :: analysis filter, 4x10 matrix, real branch low and high pass filters and imagery branch low and high pass filters
sf :: synthesis filter

Description

dualfilt1 is an utility function for obtaining second and further stage filters for dualtree complex wavelet transform. Refer to Professor Ivan Selesnick's webpage at Brooklyn Polytech, NY.
