Face recognition is typically an ill-posed problem because of the limited number of available samples. As experimental results show, combining multiclassifier fusion with the RBPCA MaxLike approach, which couples covariance matrix regularization and block-based principal component analysis...
Texture-based automatic face recognition (AFR) methods find global similarities between two faces by computing their local regional similarities. A novel method based on Fisher discriminant analysis is proposed to estimate each region's contribution to the global similarity score. Experimental...
In this article extensive computer simulation studies have been aimed at the challenging problem of electron localization in materials with disorder or defects.Here, the most efficient numerical tools and approaches that researchers have developed to study the problem are discussed.
Digital images are functions of the brightness values in 2D representations of real-world scenes. The term image processing describes computer operations carried out on digital images with some goal in mind. Such goals are related to application areas in a variety of disciplines, from art and...
HPC system architectures are shifting from the traditional clusters of homogeneous nodes to clusters of heterogeneous nodes and accelerators. The future of high-performance computing (HPC) from the technologies developed today to showcase the leadership-class compute systems, the supercomputers....
Direct visualization of higher-order data avoids the error and overhead introduced by the widely used resampling approach. Here, we give an overview of problems and solution strategies in the context of our research on higher order visualization and exemplify them using volume rendering and...
