This article describes the participation of the University and Hospitals of Geneva at three tasks of the 2007 ImageCLEF image retrieval benchmark. The visual retrieval techniques relied mainly on the GNU Image Finding Tool (GIFT) whereas multilingual text retrieval was performed by mapping the full text documents and the queries in a variety of languages onto MeSH (Medical Subject Headings) terms, using the EasyIR text retrieval engine for retrieval. For the visual tasks it becomes clear that the baseline GIFT runs do not have the same performance as more sophisticated techniques such as visual patch histograms do have. GIFT can be seen as a baseline for the visual retrieval as it has been used for the past four years in ImageCLEF in the same configuration. Whereas in 2004 the performance of GIFT was among the best systems it now is towards the lower end, showing the clear improvement in retrieval quality. Due to time constraints no further optimizations could be performed and no rele...
