Description
Calculate DiscreteWaveletTransform using different types of wavelets
This box calculates the discrete wavelet transform using the following library: http://wavelet2d.sourceforge.net/ There are differents options for the wavelet's choice like Haar,Daubechie, Biorthogonal, Coiflets, Symlets. The user must pay attention in the samples quantity sent to the box because it has to be higher than 2^J where J is the decomposition levels.
Inputs
1. Signal
Signal to be decomposed.
- Type identifier : Signal (0x5ba36127, 0x195feae1)
Outputs
There are at least 3 outputs and there is always the 'Info' output which is necessary to be connected to the 'Info' signal in the inverse discrete wavelets transform. The decompositions start with the less detailed level (low frequencies) (A) and go until the highest detailed level (high frequencies) (D1)
1. Info
Info signal (needed to export samples length)
- Type identifier : Signal (0x5ba36127, 0x195feae1)
2. A
- Type identifier : Signal (0x5ba36127, 0x195feae1)
3. D2
- Type identifier : Signal (0x5ba36127, 0x195feae1)
4. D1
- Type identifier : Signal (0x5ba36127, 0x195feae1)
Settings
You can choose the level of decomposition and the wavelet type
1. Wavelet type
- Type identifier : Wavelet type (0x393eac3e, 0x793c0f1d)
- Default value : [ bior1.3 ]
2. Wavelet decomposition levels
- Type identifier : Wavelet decomposition levels (0xf80a2144, 0x6e692c51)
- Default value : [ 2 ]
