ImageCLEF - Image Retrieval in CLEF

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.
