Video Image Annotation Tool (VIA) goes Open Source!

CERTH-ITI recently released its VIA annotation tool as open source under the GPL license.
You can check it out on SourceForge.

Video Image Annotation Tool (VIA) is a windows application to manually annotate video and images. It provides a user friendly interface for the accurate and undemanding live and "frame by frame" annotation of video and and region-based annotation of still images integrating results from a segmentation algorithm.


The development of this tool has been supported by the Bootstrapping Ontology Evolution with Multimedia Information Extraction (BOEMIE)(FP6-027538) and aceMedia(FP6-001765) projects.

The source code is available at the project's SVN repository page on SouceForge:
