Detailed Description

template<class TInputImage, class TOutputImage = TInputImage>
class rtk::ParkerShortScanImageFilter< TInputImage, TOutputImage >

Weighting of image projections to handle short-scans in tomography reconstruction. Based on [Parker, Med Phys, 1982]. Class implements a fix to typo in equation (12) of Parker as seen in book "Principles of computerized tomographic imaging" by Kak and Slaney
