Redefining how you ‘look’ at a hyperspectral image

With the powerful interactive visualization techniques in the Gerbil software, you can finally explore the raw data of your multispectral/hyperspectral image in an intuitive way. Gerbil’s rich set of algorithms including feature space transformations, dimensionality reduction, segmentation and material clustering make it the first choice for many analysis tasks.

See in the video below how a multispectral image can be visually explored in five minutes.

Gerbil is free software and runs on all major platforms.

Reading material Fri, May 12, 2017

For those curious about the concepts behind Gerbil and its underlying algorithms, we recommend the scientific article A Novel Framework for Interactive Visualization and Analysis of Hyperspectral Image Data. It is published open-access, which makes it freely available.

If you use the software in your work, please include the citation:

Johannes Jordan, Elli Angelopoulou, and Andreas Maier, “A Novel Framework for Interactive Visualization and Analysis of Hyperspectral Image Data,” Journal of Electrical and Computer Engineering, vol. 2016, Article ID 2635124, 17 pages, 2016. doi:10.1155/2016/2635124

Spanish speakers might also be interested in the student thesis Procesado de imágenes hiperespectrales by Esther Sánchez Bernabé, which gives directions about how to use the software. Note that I do not speak Spanish myself, so I cannot assess the document.

Gerbil part of ESA SOCIS 2016 Tue, Jun 14, 2016

After being very successful for the Gerbil project in the previous years, the European Space Agency continues to support us this year through their amazing Summer of Code in Space program.

This summer, Aleksander Cieślak will work on improving how processing tasks are scheduled and executed in the background for a more responsive and stable GUI.

Aleksander already worked with us last year and implemented many usability improvements to the GUI, as well as a few new visualization features.

Many thanks to ESA for their financial support and bringing together great developers like Aleksander and the Gerbil project.

Gerbil ported to Qt5 Wed, Apr 20, 2016

After a long-standing bug with framebuffers in Qt5 is fixed since version 5.5.1, we recently finished our porting of Gerbil from Qt4 to Qt5.

This is very beneficial as Qt4 had its very own problems with framebuffer support. On some Windows systems, Gerbil would crash on startup not being able to create the framebuffers it needs to display spectral plots. This seems to be solved by the switch to Qt5, as well as problems with GL context switches reported on Linux systems. Finally, the switch to Qt5 makes building easier on Windows.

See our Github project page for the current sources using Qt5. If you for some reason need to work with Qt4, we are still maintaining the Qt4 version and back-porting features to it. Find it in the qt4 branch.

New website launched Thu, Mar 10, 2016

Welcome to our new website which accompanies our move to Github for development. The new website design is responsive and also makes it easier for us to write new content.

Gerbil development, including bug tracker and feature requests moved to Github (and the main source repository from SVN to Git as well). This means the development process is more accessible and interaction with the project is made more easy by using the tools Github provides, e.g. pull requests. We had a good experience with Github last year esp. with the work of our SOCIS student. Most of his work could directly incorporated into the software and will be part of the next release.

See our Github project page with the new issue tracker.

Gerbil is a mentoring organization for ESA Summer of Code in Space! Thu, May 7, 2015

Once again (third year in a row!) we are mentoring students to work on exciting projects in a research-driven environment. Please have a look at our project ideas page and get in touch with us about your application!
