In BIIGLE, you can upload images and videos and organize them in projects and volumes. These are like directories on your computer. You can also create label trees which are collections of labels that are available for new annotations. Since BIIGLE is a web application, you can invite your colleagues into your annotation projects and annotate together. BIIGLE can handle very large image collections with tens of thousands of images. It can also handle very large images with tens of thousands of pixels on each edge. These are called mosaics because they are stitched together from lots of regular images. While some marine biologists create mosaics for annotation, too, others annotate mosaics created from aerial images or digital microscopy slides. Say goodbye to counting microbes while sitting in the lab hunched over your microscope. With BIIGLE, you can annotate digital slides from the comfort of your favorite armchair and even let your colleagues help you!

BIIGLE is developed by the Biodata Mining Group of Bielefeld University, led by Prof. Tim W. Nattkemper. While it was originally created with a focus on marine imaging, it is now used in many other areas as well. Since the source code is open and freely available (at github.com/biigle), several research institutes maintain their own application instances. The Biodata Mining Group maintains the largest public instance at biigle.de which is powered by the de.NBI cloud at Bielefeld University. As of the time this blog post is published, the main instance hosts over 2,000 users from more than 40 countries who created 14 million image and video annotations on 2 million images and videos.
