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.

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

can u please send me the code for image compression by using 'SVD'.

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.

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.

It is a only DCT encoder, instead of 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,
