      • 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.
      • 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.
      • 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.
      • 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.
