[Insight-users] Binary image to Mesh / Mesh to Binary image

[Leila Baghdadi]

It is not clear to me which of the images is the output of itkTriangleMeshToBinaryImageFilter, but if that shte image which has the last line all zeros, then you might want to go back and make sure this class gets the correct image information, I have to go back and check but I thought I had written it so that it allows the user to specify image origin and spacing or read the image information from one of the ITK ImageIO factories,

Subject: [Insight-users] Binary image to Mesh / Mesh to Binary image

Hi!So here is the thing. . .I have a segmentation in a 3D binary mask (let's call it original) and then obtained its mesh using itkBinaryMask3DMeshSource, finally I stored the itk mesh in a .vtk file using itkVTKPolyDataWriter.


Everything good so far.Then I created another function that reads the .vtk file into an itk mesh using itkVTKPolyDataReader, I get the 3D binary mask (let's call it output) from the mesh using itkTriangleMeshToBinaryImageFilter and store it as a .mhd file.


Here is the problem: when I load both my original and the output binary masks, I'm expecting them to be exactly the same BUT the last slice of my output volume turns out to be all zeros. I'm attaching an image that hopefully will describe what's happening better. . .


Does anybody knows what is causing this? and how to solve it?Thanks a lot!
