This distribution contains routines for manipulating files formatted
according to the Joint Photographic Experts Group (JPEG) standard.
Matlab's built-in IMREAD and IMWRITE functions provide basic
conversion between JPEG files and image arrays. The routines in this
package provide additional functionality for directly accessing the
contents of JPEG files from Matlab, including the Discrete Cosine
Transform (DCT) coefficients, quantization tables, Huffman coding
tables, color space information, and comment markers. It is assumed
that the user of this software has a good understanding of both the
JPEG compression standard and Matlab data structures.
This software is based in part on the work of the Independent JPEG
Group (IJG), as it makes use of IJG's free JPEG code library. If the
MEX file binaries provided in this distribution are not the ones you
need for your system, you will need to download IJG's code library and
install it on your system before compiling the source code. See
"Installing" for more details.
