<DIV> </DIV>
<DIV> I want to try apply itk::GeodesicActiveContourShapePriorLevelSetFilter on the 3D image segmentation. i have went through the example in tutorial, Here i have some questions, if anyone has done this before, please help, thanks a lot !!</DIV>
<DIV> </DIV>
<DIV>1) what will be the input and output file format for the itkSignedDanielssonDistanceMapImageFilter in 3D case?</DIV>
<DIV> </DIV>
<DIV> for now i have 10 series of dicom images, each has 40 slices, i will manually segment each slice to binary image(*.png)</DIV>
<DIV> So do i need to combine those 40 images to one mha file as input for the distance map image filter? </DIV>
<DIV> if yes, how to do that?</DIV>
<DIV> if 10 series of images has different x,y resolution and z thinkness value. how to normalize?</DIV>
<DIV> </DIV>
<DIV>2) what will be the input and output file format for the itkImagePCAShapeModelEstimator in 3D case?<BR> <BR>3) in the example of GeodesicActiveContourShapePriorLevelSetFilter, there are three seed points manually defined, however, in general case, especailly in 3D segmentation, is it necessary to do that? or any other alternative way? </DIV>
<DIV> </DIV>
<DIV>i found very limited info about this topic on internet, i really appreciate if anyone can help to answer those questions, or give me some information related to this. </DIV>
<DIV><BR>btw, thanks luis for answering my previous question, very detail and helpful.</DIV>
