int SoSeismic::computeEnvelope	(	SoCpuBufferObject *	sourceBufferObject,
		SoCpuBufferObject *	targetBufferObject,
		int	traceSize,
		int	numTrace
	)

Compute envelope (amplitude) attribute on a set of seismic traces.

• This function handles SoCpuBufferObject input output type only.
• Data stored in buffers must be of type float.

virtual int SoSeismic::computeEnvelope	(	SoBufferObject *	sourceBufferObject,
		SoBufferObject *	targetBufferObject,
		int	traceSize,
		int	numTrace
	)			[virtual]

Compute envelope (amplitude) attribute on a set of seismic traces.

amp(t) = sqrt( re^2(t) + im^2(t))

• This function can be redefined to support a different type of SoBufferObject.
• By default the SoCpuBufferObject CPU version will be used.
• Data stored in buffers must be of type float.

Parameters:

	sourceBufferObject	Should contain the real part of the complex trace (original trace data).
	targetBufferObject	should contain the imaginary part of the complex trace (Hilbert transform of trace data). Note: targetBufferObject will be overwritten with the result values.
	traceSize	Number of samples in each trace (must be same for all traces).
	numTrace	Number of traces.

int SoSeismic::computeHilbert	(	SoCpuBufferObject *	sourceBufferObject,
		SoCpuBufferObject *	targetBufferObject,
		int	width,
		int	height
	)

Compute Hilbert transform on a set of seismic traces.

• This function handles SoCpuBufferObject input output type only.
• Data stored in buffers must be of type float.

virtual int SoSeismic::computeHilbert	(	SoBufferObject *	sourceBufferObject,
		SoBufferObject *	targetBufferObject,
		int	width,
		int	height
	)			[virtual]

Compute Hilbert transform on a set of seismic traces.

The Hilbert transform is computed by convolving sourceBufferObject with a windowed (approximate) version of the ideal Hilbert transformer.

• This function can be redefined to support a different type of SoBufferObject.
• By default the SoCpuBufferObject CPU version will be used.
• Data stored in buffers must be of type float.

int SoSeismic::computeInstPhase	(	SoCpuBufferObject *	sourceBufferObject,
		SoCpuBufferObject *	targetBufferObject,
		int	traceSize,
		int	numTrace
	)

Compute instantaneous phase attribute on a set of seismic traces.

• This function handles SoCpuBufferObject input output type only.
• Data stored in buffers must be of type float.

virtual int SoSeismic::computeInstPhase	(	SoBufferObject *	sourceBufferObject,
		SoBufferObject *	targetBufferObject,
		int	traceSize,
		int	numTrace
	)			[virtual]

Compute instantaneous phase attribute on a set of seismic traces.

phase(t) = arctan( im(t)/re(t))

• This function can be redefined to support a different type of SoBufferObject.
• By default the SoCpuBufferObject CPU version will be used.
• Data stored in buffers must be of type float.

Parameters:

	sourceBufferObject	Should contain the real part of the complex trace (original trace data).
	targetBufferObject	should contain the imaginary part of the complex trace (Hilbert transform of trace data). Note: targetBufferObject will be overwritten with the result values.
	traceSize	Number of samples in each trace (must be same for all traces).
	numTrace	Number of traces.
