How can I calculate Maximum Intensity Projection for a 3D image

Hi everyone,

I am new to this community and have a question about computing MIP for a 3D image I have, with (192x192x32) dimensions. What is the simplest way of computing MIP for a 3D image?

Thanks

 max(Image,[],dim)

where dim=1,2,3 is the dimension along which you want to project.

Thanks. I did that but then how can I display the MIP as a 3D image (be able to rotate it)?

An MIP of a 3D image is a 2D image. Possibly, you mean you would like to take the MIP along arbitrary directions in 3D. For that, you would have to rotate the volume into alignment with the x,y, or z axis. Then, take the MIP along one of these major axes as above and display the result using imshow or similar...

Rotations of a volume can be done with tformarray.
