unsigned int ForIA::Wavelet::Coefficient::level | ( | ) | const [inline] |
The "level" of the frequency band to which this coefficient belongs See FrequencyBand

double ForIA::Wavelet::Coefficient::magnitude | ( | ) | const [inline] |
The amplitude of this wavelet coefficient hmm, need to rename this as it can be negative!
Definition at line 67 of file Wavelet.hh.
unsigned int ForIA::Wavelet::Coefficient::scale | ( | ) | const [inline] |
The scale parameter of this wavelet coefficient.
Definition at line 34 of file Wavelet.hh.
double ForIA::Wavelet::Coefficient::translation | ( | ) | const [inline] |
The translation parameter of this wavelet coefficient
Note: in the discrete wavelet transform the translation sampling is dependent on the scale. At the smallest scale of 2 there are N/2 points sampled from the translation axis (where N is the length of the input data sequence). At the maximum scale there will only be one sample taken from the translation axis, which ought to correspond to averaging the signal
The value returned here is the centre of the sampled translation region.

double ForIA::Wavelet::Coefficient::translationMax | ( | ) | const [inline] |
The upper bound of the sampled translation range See note on translation()
Definition at line 57 of file Wavelet.hh.
double ForIA::Wavelet::Coefficient::translationMin | ( | ) | const [inline] |
The lower bound of the sampled translation range See note on translation()
