UNCOMPRESSED IMAGE SIZE -15466248 BYTES
JPEG 2000 employs a
new type of lossless compression algorithm than the one
used in traditional JPEG compression.
Whereas traditional JPEG compresses
images with a scheme called discrete cosine transformation
(DCT), JPEG 2000 uses the newer wavelet based compression.
One of the drawbacks of the original
jpeg compression is that it tends to cause visible artifacting
with varying degrees of lossiness. Images suffer degradation
to the point of loss of visibility at extremely high compression
rates. Wavelet compression, on the other hand, uses mathematical
expressions to encode the image in a continuous stream.
Depending on the amount of compression the user applies,
the result can be completely lossless (no artifacts) and
yet produce extremely small files. (see above)
