Hi everyBody,
I have tried to use the deforableModel3DFilter to segment the liver. The =
initial mesh is derived from the applying the Marching cubes of the =
binary Image resulted of the confidencefilter of the image. The results =
in not good because the confidence filter segmented other parts of the =
image that don't belong to the liver.
Now I'm trying to use the itkBalloonForce3DFilter with a Sphere as =
initial image and the potential image the binary image I refered before. =
I'm visualizating the result and the planes sagital, coronal and axial =
of the initial image with vtk.
The problem is the the final Mesh appears at the origen of the image and =
doesn't change from the initial mesh, the final mesh is a Sphere, I =
think the problem is that the initial mesh hasn't been located well.
The code that i use to put the center is the next:
m_Center[0]=3D x;
m_Center[1]=3D y;
m_Center[2]=3D z;
m_BalloonForce3DFilter->SetCenter(m_Center);
m_SphereCenter[0]=3Dx;
m_SphereCenter[1]=3Dy;
m_SphereCenter[2]=3Dz;
m_SphereSource->SetCenter(m_SphereCenter);
With [x,y,x] an initial seed chosen by the user.
Does anybody know what hapens or know how I can to locate the initial =
mesh fine?
Thanks in advance.
Sam
