Image Indexing and Retrieval from Digital Libraries

As digital image libraries grow, methods for indexing and searching such libraries based on image content become more important. In this paper we focus on three speciic approaches to the representation of images for content-based image indexing and retrieval 13,20,29] although others will be discussed brieey. The work of 13] represents one of many methods which blends color histograms with some spatial information. The work of 20] is a multiresolution approach which indexes images in a compressed domain. There are several methods discussed in 29]|one for objects, one for shapes, and one for textures. Their common feature is that they explicitly capture the dominant geometric features of images.
