FloatWavelet(Single, Single) Constructor

Creates a wavelet from the given low-pass and high-pass decimation filters. If the orthonality condition for decimation filters h1 and h0,

Copy

h1(n) = (-1)^n h0(N - n)

is met, an orthogonal wavelet will result.

Syntax

C++

Copy

public FloatWavelet(
	float[] LowPassDecimationFilter,
	float[] HighPassDecimationFilter
)

Public Sub New ( 
	LowPassDecimationFilter As Single(),
	HighPassDecimationFilter As Single()
)

public:
FloatWavelet(
	array<float>^ LowPassDecimationFilter, 
	array<float>^ HighPassDecimationFilter
)

new : 
        LowPassDecimationFilter : float32[] * 
        HighPassDecimationFilter : float32[] -> FloatWavelet

Parameters

LowPassDecimationFilter Single: An even-length float array containing a low-pass decimation filter.
HighPassDecimationFilter Single: An even-length float array containing a high-pass decimation filter.

Exceptions

Exception	Condition
InvalidArgumentException	"All low-pass decimation filters must have a non-zero even length."
InvalidArgumentException	"All high-pass decimation filters must have a non-zero even length."

Remarks

Using symmetry relationships for orthognal perfect-reconstruction filter banks, both of the reconstruction filters are created from the decimation filters. Specifically, if h0 and h1 are the decimations filters, then the reconstruction filters will be:
f0(n) = h0(-n), and
f1(n) = h1(-n).
