The Visual Concept Detection Task in ImageCLEF 2008 [chapter]

Thomas Deselaers, Allan Hanbury
2009 Lecture Notes in Computer Science  
The Visual Concept Detection Task (VCDT) of ImageCLEF 2008 is described. A database of 2,827 images were manually annotated with 17 concepts.  ...  The runs were evaluated using ROC curves, from which the Area Under the Curve (AUC) and Equal Error Rate (EER) were calculated. For each concept, the best runs obtained an AUC of 80% or above.  ...  As for the object detection task in 2007 [1] , a web interface was created for manual annotation of the images by the concepts.  ...
