## Project history and usage

EPSILON is an open-source wavelet image compressor. The official SourceForge project page and wiki describe it as aimed at parallel and robust image processing.

### Project history

The SourceForge project was registered on October 2, 2006. Its public project metadata lists a last update of June 17, 2014, suggesting a mature but quiet utility rather than an actively evolving media stack.

### Adoption history

EPSILON's visible adoption is narrow: it is packaged by Homebrew in this dataset and hosted on SourceForge with code, wiki, tickets, mailing lists, and file releases. The official page lists BSD, Linux, and Windows as operating systems.

### How it is used

The package provides an epsilon command plus helper scripts for starting and stopping EPSILON nodes, fitting its stated focus on parallel image-processing workflows.

### Why package nerds care

EPSILON is interesting mostly as a niche compressor: wavelet-based, command-line friendly, and old enough to preserve a SourceForge-era image-processing project in modern package managers.

### Timeline

- 2006: SourceForge project registered.
- 2014: SourceForge project page lists its last update.

### Related projects

- The project is adjacent to other command-line image-compression and image-processing tools, but no direct upstream companion project is documented in the official sources.
