Overrides:

apply in class SimpleOperator

Parameters:

signal - DiscreteSignal

roi - Region of Interest

Returns:

RealSignal

apply

protected Signal apply(RealSignal signal)

Performs the Log function on a RealSignal. Returned Signal is a RealSignal (signal is not modified).

Overrides:

apply in class SimpleOperator

signal - RealSignal

Returns:

RealSignal

apply

protected Signal apply(RealSignal signal,
                       ROI roi)

Performs the Log function on a RealSignal in a region of interest. Returned Signal is a RealSignal.

Overrides:

apply in class SimpleOperator

Parameters:

signal - RealSignal

roi - Region of Interest of signal

Returns:

RealSignal
