In this paper we describe our experiments in High-level feature extraction (HLF) and Search tasks of the 2009 TRECVid evaluation. This year, we have concentrated mainly on the local (affine covariant) image features and their transformation into a searchable form, especially using the indexing techniques.

In brief, we have submitted the following runs:

  1. HLF: We have used training method based on support vector machine (SVM) using five types of global and local image features. Results were submitted in the BRNO_HLF_SI run.

  2. Search: We have performed a fully automatic experiment based on the transformed local image features together with face detection and global features - color layout and texture features in the BrnoUT_visual.2 run.

The paper is organized as follows. In Section 1, a motivation and an overview of the work is presented. We dedicated Section 2 to the feature extraction task, which is being used in common by the HLF and Search tasks. Details of the tasks we have sent are given in Section 3 and Section 4. Finally, Section 5 discusses the achieved results and concludes the paper. The result tables are attached at the end of the paper.
