High throughput block coding in the HTJ2K compression standard
2019 IEEE International Conference on Image Processing (ICIP), 2019•ieeexplore.ieee.org
This paper describes the block coding algorithm that underpins the new High Throughput
JPEG 2000 (HTJ2K) standard. The objective of HTJ2K is to overcome the computational
complexity of the original block coding algorithm, by providing a drop-in replacement that
preserves as much of the JPEG 2000 feature set as possible, while allowing reversible
transcoding to/from the original format. We show how the new standard achieves these
goals, with high coding efficiency, and extremely high throughput in software.
