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
