If you'd started working on writing your own code the first time you asked
pretty much this EXACT question with a subject that is a permutation of the
words "matlab", "video", and "compression" you'd probably have at least a
basic compression function working by now.

If this is part of YOUR research (as you said in one of your previous
postings) then YOU need to write YOUR code. People here are generally
willing to _help_ people that have problems while writing their code, but
you need to show you've put in some effort first.

Hi,

As you said i have asked this question many times but unfortunatly no one give me any idea about this issue also i have search in the web. i have done compression the extraction image well , but after compressing the images how can create the compressed image concerning omitting the similar images.
i.e suppose i have extracting a cerftain video to 120 images and i have compressed all the images and after that i want to re-extract the video by omitting the similar images then rebuild the video.
as you are the big expert in this issue please just give me an ideas for this issue.

I don't know who you are addressing that to... I do not recall any video
experts here.

It sounds as if you want to work with the strategy of using key frames
and difference frames. If I recall, that strategy is used by MPEG2,
which you should be able to find a fair bit of literature about. I seem
to recall that the terminology used is "I frames" and "D frames".
