Hello there, I am working on MRI slices, while working i found that there are some slices is missing and that causing losing in the information. So, i need to interpolate each 2 consecutive slices to generate a new slice between them. i have used the following code to interpolate two different meshgrids, how i can apply this code on the images i attached?
% Create two initial surfaces (different grids)
[x1,y1] = meshgrid(-2:0.4:2,-2:0.4:2);
[x2,y2] = meshgrid(-2:0.2:2,-2:0.2:2);
z1 = x1.*exp(-x1.^2 - y1.^2);
z2 = x2.*exp(-x2.^2 - y2.^2) + 1;
figure
h1 = surface(x1,y1,z1);
hold on
h2 = surface(x2,y2,z2);
view(3)
% Interpolate surface z1 in the finer grid defined for surface z2
z1_interp = interp2(x1,y1,z1,x2,y2);
a = 0.3;
hold on
h3 = surface(x2,y2,(a*z1_interp + (1-a)*z2));

A better idea is to resample from the full 3d stack. Then you would be able to use more advanced interpolation tools.
