Function Documentation

HxImageRep L_HXIMAGEREP HxWatershedMarkers (  HxImageRep    input,
HxImageRep    mask,
int    conn = 4,
bool    doLabelMask = false
) 
 

Watershed from markers.

  • im is the input image (HxImageRep)
  • mask is the marker image (HxImageRep)
  • conn is the connectivity (4 or 8)
  • doLabelMask (bool) indicate whether the marker images needs to be labeled before, or not
Returns:
the watershed Image, ImageRep
Remarks:
this version of watershed does not consider a cost function. See HxWatershedMarker2, for a cost-based implementation
