Entropy Encoding EBCOT-Embedded Block Coding with Optimized Truncation-In JPEG2000
JPEG2000 is the new standard for the compression of images,
which succeeds to JPEG. It’s has a much higher algorithmic
complexity. The complexity of the entropy encoder ( EBCOT) is
the most significant in JPEG2000. Which alone
constitutes about 70% of the overall processing
time for compression of an image.
This new standard has many features and characteristics
(region of interest, several types of decompression). In this
paper we are interested on studying the
algorithm of JPEG2000 and the most complex
in the JPEG2000 compression
process, the EBCOT entropy encoder, and its performance are
presented.
