Hi
I have JPEG compressed data, as shown in below figure.

How original image can be recovered, if Height & Width of original image is known.
BTW, below is how the original image should look like.

My final intension to perform this on GPU, to speed it up for live streaming. (every millisec is important)
I am also attaching the compressed data in '.mat' format

I strongly recommend to ask an internet search engine for "Matlab jpeg decompress". You will find many solutions and such a short research is much faster than waiting for the forum to answer.
I speed matters, do not use Matlab for this task but one of the many libraries written in faster languages. Doing this on a GPU might have the drawback, that the data transfere might be the bottleneck.
