Converting a Multiframe Image to a Movie

To create a MATLAB movie from a multiframe image array, use the immovie function. This example creates a movie from a multiframe indexed image.

```
mov = immovie(X,map);
```

In the example, X is a four-dimensional array of images that you want to use for the movie.

You can play the movie in MATLAB using the movie function.

```
movie(mov);
```

This example loads the multiframe image mri.tif and makes a movie out of it. It won't do any good to show the results here, so try it out; it's fun to watch.

mri = uint8(zeros(128,128,1,27)); 
for frame=1:27
    [mri(:,:,:,frame),map] = imread('mri.tif',frame);
end

mov = immovie(mri,map);
movie(mov);

Note that immovie displays the movie as it is being created, so you actually see the movie twice. The movie runs much faster the second time (using movie).

Note To view a MATLAB movie, you must have MATLAB installed. To make a movie that can be run outside MATLAB, use the MATLAB avifile and addframe functions to create an AVI file. AVI files can be created using indexed and RGB images of classes uint8 and double, and don't require a multiframe image.
