fScan Reference Manual, Chapter 2 (CmdLineOptions:Expr): erode

Erode -- Erode edges of an intensity region in a 3D image volume

usage: -expr [NREPTS] [static] erode val maskbits newval flag nmatch nneighbors

VAL - “Inside” value (or Percent value if (FLAG & (4|8))
MASKBITS - voxel data values to consider for comparing with VAL (DATABITS is inverse of MASKBITS)
NEWVAL - bit-value to turn on when adding (dilating) a voxel. If NEWVAL is negative and MASKBITS is zero, then the input data voxel value will be used when dilating into neighboring voxels.

FLAG:

  • 0 - (default)
  • 1 -
  • 2 - erode/dilate in 2-D plane only
  • 4 - Stop on dark edge (voxel darker than (100-VAL1)% of inside neighbors (Needs MASKBITS set)
  • 8 - Stop on bright edge (brighter than (100+VAL1)% of inside neighbors
