biorfilt

bi-orthogonal wavelet filter set

Calling Sequence

[Lo_D,Hi_D,Lo_R,Hi_R]=biorfilt(DF,RF)

Parameters

DF
: analysis scaling filter
RF
: synthesis scaling filter
Lo_D
: lowpass analysis filter
Hi_D
: highpass analysis filter
Lo_R
: lowpass synthesis filter
Hi_R
: highpass synthesis filter

Description

orthfilt is an utility function for obtaining analysis and synthesis filter set of given bi-orthogonal spline wavelets. DF and RF should be output of biorfilt result with the same length.

Examples

[RF,DF]=biorwavf('bior3.3');
[lo_d,hi_d,lo_r,hi_r]=biorfilt(DF,RF);
