An online facial expression recognition system based on personalized galleries is presented. This system is built on the framework of the PersonSpotter system, which is able to track and detect the face of a person in a live video sequence. By utilizing the recognition method of Elastic Graph Matching, the most similar person whose images are stored in the(More)
This paper summarizes the Bochum/USC face recognition system, our preparations for the FERET Phase III test, and test results as far as they have been made known to us. Our technology is based on Gabor wavelets and elastic bunch graph matching. We brieey discuss our technology in relation to biological and PCA based systems and indicate current activities(More)
Integrated media workstations are increasingly being used for creating, editing, and monitoring sound that is associated with video or computer-generated images. While the requirements for high quality reproduction in large-scale systems are well understood, these have not yet been adequately translated to the workstation environment. In this paper we(More)
A novel elastic image registration approach is proposed, which can register both 2D medical images and gel electrophoresis automatically and accurately. Firstly, the global affine registration method based on image intensity is used to initialise a starting estimation of the robust registration algorithm. Then, by using iterative landmark based algorithm,(More)
Increasing women's participation in computer science is a critical workforce and equity concern. The technology industry has committed to reversing negative trends for women in computer science as well as engineering and information technology "computing" fields. Building on previously published research, this paper identifies factors that influence young(More)
Metallic alloys show complex chemistries that are not yet understood so far. It has been widely accepted that behind the composition selection lies a short-range-order mechanism for solid solutions. The present paper addresses this fundamental question by examining the face-centered-cubic Cu-Zn α-brasses. A new structural approach, the(More)
Through surveys of 1,673 students, 1,685 parents, 1,013 teachers, 9,693 principals, and 1,865 superintendents across the United States, this study explores perceptions, access, and barriers to computer science education at the K-12 level. We found most respondents were unable to distinguish computer literacy activities from computer science, with female,(More)
Human stem cell-like memory T (Tscm) cells are long-lived, self-renewing memory lymphocytes that can differentiate into effector cells and mediate strong antitumour response in murine model. The distribution and function of Tscm cells in human lung cancer remain unknown. In this study, we investigated the properties of human Tscm cells in the blood and(More)
