3 D interpolation

[uradit...@gmail.com]

Hello Folks !

I was having two MRI slices,aim was to interpolate a third slice
inbetween.
I performed watershed segmentation for it,then did Delaunay
Triangulation over both segmented slices.
Then..found nearest neighbourhood points in both 2D slices.Now aim is
to find 3rd slice points,which i can interpolate using points obtained
form above two slices.
But but...problem is..both of them have unequal points...
How shud I now go ahead !!

Any help regarding this will be really appreciable

Thanks in advance
Regards

Adi

Try this
I(:,:,1) =imread('mri.tif',13);
I(:,:,2) =imread('mri.tif',14);
I = double(I);
J = interp3(I);

The mri.tif file comes inbuilt with the matlab image processing
toolbox, so you would have to get it confirmed from mathworks in this
case. But having a look at those images, I feel they are actual
images and not segmented.
