Eos is an electron microscope image analysis software developed and published since 1996 by Takeyuki Wakabayashi and Takuo Yasunaga. Originally was a collection of programs of 50 or so. Then by software development with students, it is an integrated environment that is composed of program of about 400 on the electron microscope image processing, currently.

Overview of Eos

 Eos is named using first letters of "Extensible Object-oriented System" after the goddess of the dawn Eos in Greek mythology. We have the hope that many programs will be developed from here. We think there is a strong transmission for many of the commands and rapid development, and the development of effective programs for the user through integration. At present, it is referred to as a platform that such program environment is established, but it was called "environment" because it was not a word popular development at that time.

1996 - 2011

 Eos system supplies four types of codes. We provid two of them for Developers, other two for Users. The support for Developers of the former are Object-oriented library and Prototype and Source code, the support for Users of the latter are Small Tools of viable and Integration program that integrates them. Integration program is one that is provided as part of the command as Display2, and Makefile( In the future, integrating to PIONE with GUI) for make.

2011年〜

We added the class of Experts to categories such as the Users and the Developers. One fo the Experts is the layer that can be programmed in the scripting language level and electron microscope image processing. In addition, it was running by integrating of make through shell script initially, after that the time has change when computing environment itself become cloud and cooperative computing systems, so we decided to achieve the transformation to a platform to help them. It is developing, however we aim to the Enhancement of the layers of the scripting language and the level including those related to the display, such as a GUI.

And we describe Loadmap about the direction of future development.


Eos is an environment for image analysis of electron micrographs. Eos system supplies four types of codes.
