ImageCLEF – The CLEF Cross Language Image Retrieval Track.
The European side of working with digital video.
From the 2009 event website:
ImageCLEF is the cross-language image retrieval track run as part of the Cross Language Evaluation Forum (CLEF) campaign. This track evaluates retrieval of images described by text captions based on queries in a different language; both text and image matching techniques are potentially exploitable.
