High-level feature extraction We describe our system for the task of HLF extraction in TRECVID 2008. Features at different granularities are extracted to describe visual content of keyframes, and four classifiers for each concept are trained by SVM, and different fusion strategies are used to combine final results. The brief introduction to each run is shown in the Table 1.1. Table 1.1. MAP and...

This article describes the participation of the Geneva University Hospitals and the University of Geneva at the 2008 ImageCLEF image retrieval benchmark. We concentrated on the two tasks concerning medical imaging. The visual information analysis is based on the GNU Image Finding Tool (GIFT). Other information such as textual information and aspect ratio are integrated to improve the results. T...

DCU participated in the ImageCLEF 2008 photo retrieval task, submitting runs for both the English and Random language annotation conditions. Our approaches used text-based and image-based retrieval approaches to give baseline retrieval runs, with the highest-ranked images from these baseline runs clustered using K-Means clustering of the text annotations. Finally, each cluster was represented b...

This paper describes the SINAI team participation in the ImageCLEF campaign. In this paper we only explain the experiments accomplished in the medical task. We have experimented with query expansion and the text information of the collection. For expansion, we carry out experiments using MeSH ontology and UMLS separately. With respect to text collection, we have used three different collections...

The EMCSR took place in Vienna (Austria) from March 25th until 28th. The venue was at the main building of the University of Vienna, located downtown of Vienna. EMCSR 2008 was opened in the forenoon inside the impressive Great Festival Hall of the University. The EMCSR conference is taking place biennial since 1972. Thus, my impression is that everything was like two years before in 2006. The c...

This paper describes the SINAI team participation in the ImagePhoto CLEF campaign. Last years translation approaches and different Information Retrieval systems were tested. In 2008 the imagePhoto task does not include multilingual queries, so translation methods are not necessary. This year the baseline experiment uses the parameters that obtain the best results in past campaigns. The novelty ...

Wheat is the dominant cereal crop constituting the first staple food in Iran. This paper studies the energy consumption patterns and the relationship between energy inputs and yield for Wheat production in Iranian agriculture during the period 1986 – 2008. The results indicated that total energy inputs in irrigated and dryland wheat production increased from 29.01 and 9.81 GJ ha-1 in 1986 to 44...
