Minimum Probability of Error Image Retrieval: From Visual Features to Image Semantics

The recent availability of massive amounts of imagery, both at home and on the Internet, has generated substantial interest in systems for automated image search and retrieval. In this work, we review a principle for the design of such systems, which formulates the retrieval problem as one of decisi...

Multidimensional Filter Banks and Multiscale Geometric Representations

Thanks to the explosive growth of sensing devices and capabilities, multidimensional (MD) signals — such as images, videos, multispectral images, light fields, and biomedical data volumes — have become ubiquitous. Multidimensional filter banks and the associated constructions provide a unified frame...

Markov Random Fields in Image Segmentation

This monograph gives an introduction to the fundamentals of Markovian modeling in image segmentation as well as a brief overview of recent advances in the field. Segmentation is considered in a common framework, called image labeling, where the problem is reduced to assigning labels to pixels. In a
