Abstract

In recent years, query-by-semantic-example (QBSE) has become a popular approach to do content based image retrieval. QBSE extends the well established query-by-example retrieval paradigm to the semantic domain. While various authors have pointed out the benefits of QBSE, there are still various open questions with respect to this paradigm. These include a lack of precise understanding of how the overall performance depends on various different parameters of the system. In this work, we present a systematic experimental study of the QBSE framework. This can be broadly divided into three categories. First, we examine the space of low-level visual features for its effects on the retrieval performance. Second, we study the space of learned semantic concepts, herein denoted as the ldquosemantic spacerdquo, and show that not all semantic concepts are equally informative for retrieval. Finally, we present a study of the intrinsic structure of the semantic space, by analyzing the contextual relationships between semantic concepts and show that this intrinsic structure is crucial for the performance improvements.
