Concepts and Techniques for Indexing Visual Semantics
Alejandro Jaimes, Shih‐Fu Chang · 2001
In this chapter, the authors discuss content-based retrieval, emphasizing that visual information can be indexed at multiple levels. In particular they discuss a conceptual framework to index visual content and analyze different content-based information retrieval (CBIR) approaches from the perspective of the conceptual framework. A distinction is made between the interface and indexing components of CBIR systems, the advantages and limitations of different interface modalities are outlined, and the benefits of different indexing mechanisms are discussed. The discussion, which is carried out in the context of the conceptual framework for indexing visual information, shows the importance of object-level indexing techniques in CBIR. As a result, a brief overview of some of the major object-recognition strategies is presented, particularly in relation to CBIR.
