The IAPR Benchmark for Assessing Image Retrieval Performance in Cross Language Evaluation Tasks

This paper describes a new image collection created for the CLEF (Cross Language Evaluation Forum) cross-language image retrieval (ImageCLEF) track. This royalty-free collection provides additional evaluation data for ImageCLEF, and in particular provides a new collection for the ad-hoc retrieval task over the existing St. Andrews historic photographic collection. This new image benchmark (referred to as IAPR Benchmark), has grown out of an initiative started by the International Association of Pattern Recognition (IAPR) and consists of approximately 25,000 images from a personal photographic collection provided by the lead author. The construction and composition of this unique image collection are described in this paper, together with information on expected use of this image collection in future ImageCLEF tasks.
