MATLAB: Separating Ellipsoids

image processing

Hi everyone, I have an image processing question. I have a bunch of binary ellipsoids and some of them touch each other (forming what looks like a "8"). Can anyone suggest a method to separate the two ellipsoids?

Thanks in advance

You need to use watershed()

See the help for the ROTATE function.

For example:

[x, y, z] = ellipsoid(0,0,0,5.9,3.25,3.25,30);
S = surfl(x, y, z);
colormap copper
axis equal
xlabel('X')
ylabel('Y')
zlabel('Z')
pause %  Push return to see the rotation take place.
rotate(S,[0 0 1],45)
