ViXeN: View eXtract aNnotate Multimedia Data

Post provided by KadaMbari Devarajan

At a time when data is everywhere, and data science is being talked about as the future in different fields, a method that produces huge amounts of multimedia data is camera-trapping. We need ways to manage these kinds of media data efficiently. ViXeN is an attempt to do just that.

Camera traps have been a game-changer for ecological studies, especially those involving mammals in the wild. This has resulted in an increasing amount of camera trap datasets. However, the tools to manage camera trap data tend to be very specific and customised for images. They typically come with stringent data organisation requirements. There’s a growing amount of multimedia datasets and a lack of tools that can manage several types of media data.

In ‘ViXeN: An open‐source package for managing multimedia data’ we try to fix this visible gap. Camera trap management is a very specific a use-case. We thought that the field was missing general-purpose tools, capable of handling a variety of media data and formats, that were also free and open source. ViXeN was born from this idea. It stands for View eXtract aNnotate (media data). The name is also an ode to the canids I was studying at the time which included two species of foxes.

Achieving Reproducibility in Research

Earlier this month Leila Walker attended a panel discussion imparting ‘Practical Tips for Reproducible Research’, as part of the Annual Meeting of the Macroecology Special Interest Group (for an overview of the meeting as a whole check out this Storify). The session and subsequent drinks reception was sponsored by Methods in Ecology and Evolution. Here, Leila reports back on the advice offered by the panel members.

For anyone interested in viewing further resources from the session, please see here. Also, you may like to consider attending the best practice for code archiving workshop at the 2016 BES Annual Meeting. Do you have any tips for making your research reproducible? Comment on this post or email us and let us know!

This year’s Annual Meeting of the Macroecology SIG was the biggest yet, with around 75 attendees and even representation across the PhD, post-doc and faculty spectrum. The panel discussion aimed to consider what reproducibility means to different people, identify the reproducibility issues people struggle with, and ultimately provide practical tips and tools for how to achieve reproducible research. Each of the participants delivered a short piece offering their perspective on reproducibility, with plenty of opportunity for discussion during the session itself and in the poster and wine reception that followed.
