[Insight-users]problem with ItkConnectedThresholdImageFilter

[Alireza Salamy]

hi luis and all users,
  I try to apply ConnectedThresholdImage filter to segment the fiducial 
markers of my MRI image but the output image of mine is completely 
black.I choose the coorect position for seed point and I think that I chose 
a correct threshold values.The input of the algorithm is a 3D volum 
image which I made it by ITK from a series of DICOM Slices of MRI in 
format of DCM  and the output which is completely black is DCM also.can 
anybody tell me whats wrong?
  I forget to state that I remain the pixeltype as float when I instantiat the image.
