JPEG 2000 is based on the discrete wavelet transformation (DWT), scalar
quantization, context modeling, arithmetic coding and post-compression
rate allocation.
JPEG 2000 provides random access (i.e. involving a minimal decoding)
to the block level in each sub-band, thus making possible to decode
a region of the image without having to decode it as a whole. These
two features could be very advantageous in applications such as digital
libraries.
From a functionality point of view JPEG 2000 is a true improvement,
providing lossy and lossless compression, progressive and parseable
bitstreams, error resilience, region of interest, random access and
other features in one integrated algorithm. Concerning error resilience
JPEG 2000 offers higher protection than JPEG, as shown in the previous
section.
JPEG 2000 provides the most flexible solution, combining good compression
performance with a rich set of features. At present we can offer you our last software which
can code from BMP to JPEG 2000 and WLT and can decode from these formats
back into BMP one by one files or file packages.
This software allows to code data with different quality, to look
results of coding and to save the best results.
Besides, we have java-applet for decoding of JPEG 2000 formats. Applet
has a possibility of separatly-layer decoding. If your problem is
connected with graphic information processing, our software and codec
based on JPEG 2000 is necessary for you. If you are interested in
testing of software or purchase, may be in a more modified kind, please
do not hesitate to contact us.
