Loop?
for K = 1 : number_of_frames
this_frame = frames{K}; %or however you stored them
now do something with this_frame
end

That code will apply whatever onto each frame. Your code to do something with the frame is within the loop, so it gets presented with one frame at a time, in sequence.
Perhaps your question has to do with storing the results as you go. In that case have a look at

See my demo, attached. I calculate a background frame comprised of the last few frames, and then subtract it from the current frame. You can do something similar with whatever operation you want to do.

I doubt she'll answer, after more than 5 years, but I will. Is there something wrong with my code that doesn't work for you? Did you adapt it? Attach your adapted code.

i have converted the videos into frames and now I want to subtract one frame from another like frame 1-frame 2 and then frame 2-frame3 and so on till the video ends.

Did you see my answer? That's basically what I do. Adapt it as needed. It should be trivial.

Yes sir I saw your answer but my question is different.
I want to subtract the frames and continously run the loop for the whole video frames.
ex-frame 1-frame 2 and show the result in graph and then frame 2 - frame 3.Individual ans shown on graph
Sorry if I m unable to explain you clearly
