Hi, all. I want to make a steganography program using LSB in matlab. I use animated GIF for the cover object. As we know that Animated GIF is a file that consists of many images. So, can anyone tell me: How to get the frame number of this file in matlab? Thanks before.

Please explain again, what you want to get? The number of images an animated GIF consists of?

Read all of the frames using imread(), and then look at the size of what is returned.

Then "get the frame number" is equivalent to "get the number of frames" - correct? Actually a question, which should be answered by the OP...

allframedata = imread('YourFile.GIF', 'frames', 'all');
alldimensions = size(allframedata);
number_of_frames = alldimensions(end);
