Good morning to everybody, I have several confocal images captured by a Zeiss microscope. The x,y resolution is higher that z one and to perform binary volumetric operations the resolution on the three axis should be the same.

For this reason I extract from the input information matrix{} the vectorZ, than compute the supersampling using imresize to create the new 3D structure matrixZ

 x = [1,1,1];
 h = @(x) gaussmf(x,[4,0]);
 Zplanes = planes * 7;
 [r,c] = size(matrix{1,1});
 matrixZ = zeros (r,c, Zplanes);
 for i = 1: r
    for j = 1 : c
        vectorZ = zeros(1,6);
        for z = 1 : planes
        vectorZ(1,z) = matrix{1,z}(i,j);
        end
        vectorCZ(1,:) = filter(h(x),2,vectorZ(1,:));
        V2 = imresize(vectorCZ, [1 Zplanes], 'bilinear');
        matrixZ(i,j,:) = V2(1,:);
    end
   i     
end
