Detailed Description

template<class TInputImage, class TOutputImage>
class rtk::LUTbasedVariableI0RawToAttenuationImageFilter< TInputImage, TOutputImage >

Performs the conversion from raw data to attenuations.

Performs the conversion from raw data to attenuations using a lookup table which is typically possible when the input type is 16-bit, e.g., unsigned short. The I0 value (intensity when there is no attenuation) is assumed to be constant and can be changed.

If the input is of type I0EstimationProjectionFilter, then the member I0 is not used but the estimated value is automatically retrieved.

The lookup table is obtained using the following mini-pipeline:
