JPEG Compression

04 Jan 2004 (Updated 06 Jan 2004)

An example for jpeg compression and the restoration.

File Information
Description	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.
Acknowledgements	This submission has inspired the following: Image Compression
