Detailed Description

Phase Region Expanding Labeller for Unwrapping Discrete Estimates (PRELUDE).

This performs 3D phase unwrapping of images. Receives as input a complex image of any type and outputs the phase as type float. It also requires a second input of labeled phase components, which may be created using vtkImageFindPhaseLabels. This filter is a VTK implementation of the method described in the following paper:

Mark Jenkinson, "Fast, Automated, N-Dimensional Phase-Unwrapping Algorithm", Magnetic Resonance in Medicine 49:193-197 (2003).

Contains portions of code from the FMRIB Software Library.

virtual void vtkImagePRELUDE::SetNumberOfSlicesPerVolume ( int ) [virtual]

Number of slices per volume (default is undefined). If multiple volumes exist and UnwrapOperation is set to VTK_PRELUDE_UNWRAP_3D then, NumberOfThreads should be set such that the split extents are a multiple of this value. If UnwrapOperation is set to VTK_PRELUDE_UNWRAP_4D then this value must be set!
