The attached utility is a work I've submitted to the university. It shows what a jpeg compression is all about.
The function implements the DCT transform, using a matrix operator. Note that MATLAB has a function for the DCT and iDCT transforms that might be more efficient.
read the ReadMe.txt for some details about the algorithm.
If you like this file, please rate it.
enjoy,
Ohad Gal.

Doesn't seem to comply with the JPEG standard. For example, no run length encoding.

Thanks Ohad, some great stuff you have here. I've been trying out your code and I only really need to use the higher and lower compression qualities of 'image 8', which displays all the levels of quality. I can't seem to manipulate the code correctly to only use this method, section 1.8 i think, can anyone help with this? Thanks and all the best.

good jop
It is great help to me.thanks for the code
Extremely helpful, there could also have been another piece of code which could compress/uncompress any given input image.
Excellent. 11 figures ! All are great. Thanks and well done.
NO COMMENT
thanks
good work
thanks
that was a good one.well sir this is a student doing a project in image compression.well i needed a favour from you...well if u can clarify our small queries,we would be very greatful to you.
goood
very good
good
I got very helpful for me
I LOVE YOU!!!
This is I Need!!
i like it
good
The comment were written very well and thank you for this help
computer science
It is a only DCT encoder, instead of JPEG.
very good
how to use?
nice work keep doing
good
great
it is very goodand helpfull.
very good
I am very interested in it for i am found of
image processing.
IT IS GOOD
hai im a DSP programmers it seems this paper has helped me alot in implementing my compression of data
EFFICIENCY OF PROGRAM IS EXCELLENT
i will try any way good job
very fool
good
this file really shows a good example for JPEG...
hi Ohad,
i wondered if you knew of a link where i could get the matlab implementation of JPEG2000.i stumbled on your code but realized this is for jpeg.any help will be greatly appreciated. Thanks in advance!
cheers,
Rina
nice
I really need source code of JPEG image compression and decompression.plz send it to me if u can find out.
interesting for my project hardware inplementation
rachid
Its good, but I realy need the program/source code for JPEG2000.
its too good im impressed
Useful for my research
good. thx,man...
nice work.
this work is agood
