How to display/extract the different frames from a multiframe image?

Hello,

I have an image which consists of 25 frames. My goal is to convert the images to binary and then calculate the perimeter using the bwperim() function. however, I'm having trouble calling each of the frames. I've tried the montage() function to no avail. I've used the imread() function but that only reads the first frame of the image.

Does anyone have any suggestions as to what I could do?

"multiframe image"

Is the video or multiple dimention image, like 3-D (2D slices)?

A gif file would probably be more accurate. It contains time lapse images.
