Method Detail

computeHilbert

public int computeHilbert(SoBufferObject sourceBufferObject,
                          SoBufferObject targetBufferObject,
                          int width,
                          int height)

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.

computeHilbert

public int 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.

computeInstPhase

public int 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.

computeEnvelope

public int computeEnvelope(SoBufferObject sourceBufferObject,
                           SoBufferObject targetBufferObject,
                           int traceSize,
                           int numTrace)

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.

computeInstPhase

public int computeInstPhase(SoBufferObject sourceBufferObject,
                            SoBufferObject targetBufferObject,
                            int traceSize,
                            int numTrace)

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.

public int 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.
