Visual Concept Detections for the IAPR Dataset of ImageCLEF 2008

Here we will regularily add new concept annotations for images in the IAPR database for use in the photo retrieval task.

Annotations

• Annotations created by Thomas Deselaers from RWTH Aachen University.

  The method employed follows the paper:
  
  Deselaers, T., Keysers, D., Ney, H., "Discriminative Training for Object Recognition using Image Patches", CVPR, vol. 2, San Diego, CA, USA, IEEE, pp. 157-162, 20/06/2005.

  The Annotation files:

  • Annotation of the 20000 database images
  • Annotation of the topic images
• Annotations created by Jean-Michel Renders from XEROX Europe:
  • Annotations for the 20000 database images
  • Annotations for the topic images

The method used for these annotations is best described in
Fisher Kernels on Visual Vocabularies for Image Categorization. Florent Perronin and Chris Dance In: CVPR 2007, 18-23 June 2007, Minneapolis, Minnesota, US.

The annotations follow the submission format of the VCDT and the values are predicted probabilities for the concepts to be contained in the images.
