Aibu is an image sequence annotator developed and used by the VOT challenge. It can annotate sequence of images and provides several handy features such as interpolation and per-frame label annotations.
The annotator was until now only used within the VOT challenge organization and is therefore considered an alpha level software. A lot of features are missing or are not fully polished. If you find such a case you are welcome to open an issue report on Github.
The annotator is written in Java and can be built using Ant build tool. It depends only on the coffeshop library.
There is a short user guide available in the docs folder that should present most of the functionality of the interface.
