Abstract

Content-based image retrieval (CBIR) is a new but widely adopted method for finding images from vast and unannotated image databases. In CBIR images are indexed on the basis of low-level features, such as color, texture, and shape, that can automatically be derived from the visual content of the images. The operation of a CBIR system can be seen as a series of more or less independent processing stages. As there exists multiple choices for each of these stages, a multitude of CBIR systems can be implemented by combining a set of common building blocks. In this paper, we present a comparison of different techniques for three consecutive stages of a CBIR system. These include: (1) the initial per feature selection of considered images, (2) the combination of the lists of selected images, and (3) the final selection of images based on all available features simultaneously. The results of the performed experiments show that CBIR systems can be implemented using consecutive stages where, at each stage, a number of parallel techniques can be provided.
