EPSILON 0.8.1 released

EPSILON is a powerful Open Source wavelet image compressor.
The project is aimed on parallel and robust image processing.

The main feature of this release is speed improvement.
Several performance-critical parts of the library were
optimized and now EPSILON runs about 30% faster than
previous version.

Other features:
- Fine rate control
- Perfect reconstruction quality
- More than 30 wavelet filters
- Huge file support (>> 4Gb)
- Multi-threading support (for SMP machines and multi-core CPUs)
- Message Passing Interface support (for powerful clusters)
- Fault-tolerant storage format
- Clear architecture layout
- Exhaustive API documentation... read more

EPSILON 0.6.1 released

EPSILON is a powerful Open Source wavelet image compressor. The project is aimed on parallel and robust image processing.

Due to multi-threading support EPSILON runs full-speed on multi-core CPUs and SMP machines. Another exciting feature is clustering support. You can distribute image processing on several machines linked with a high-capacity network!

Among other features EPSILON supports more than 30 wavelet filters and can handle very large files (>> 4 Gb).... read more

EPSILON 0.5.1 released

Cheers! EPSILON 0.5.1 is available for download!
The main feature of this release is
multi-threading support. Now EPSILON runs full
speed on SMP machines! EPSILON decoder is
improved in terms of fault-tolerance: even
heavily-corrupted and malformed images can
be synchronized and decoded. This release
also includes some bug fixes. So, at every
turn EPSILON becomes better, faster and robust!

EPSILON 0.4.1 released

EPSILON 0.4.1 is available for download! The main feature in new release is two-pass variable bit-rate (VBR) encoding mode. VBR mode gives essential image quality boost. Another feature is a command for graceful file truncation. And the last but not the least, we added handy user manual. Enjoy!

EPSILON 0.3.1 released

Cheers! EPSILON 0.3.1 is available for download!
There is a number of changes in this release. First of all, a lot of useless code is removed. The program was substantively refactored and now looks much more pretty. New feature in this release is a large file support: now EPSILON can process HUGE images!
