Magnetic resonance (MR) tissue volume calculation is very important in medical diagnosis. A general approach is to first perform image classification of desired tissue substances slice by slice and then calculate tissue volumes via classified data samples in each slice. Two issues are generally involved; (1) selection of training samples which are slice-dependent, i.e., each slice requires its own specific training samples and (2) classification which must be carried out slice by slice individually because training samples obtained from one slice are not necessarily applicable to another. We develop a volume sphering analysis (VSA) approach which can process all MR image slices as one single image cube to calculate tissue volumes via image classification using only one set of training samples that is obtained from a single image slice. The proposed VSA using one set of training samples not only performs comparably to that using training samples specifically selected for individual image slices, but also saves significant amounts of selecting training samples and computing time.

Shih-Yu Chen received the BS degree in Electrical Engineering from Da-Yeh University in 2005, and the MS EE degree from National Chung Hsing University in 2010. He is currently a PhD (EE) student at UMBC. Mr. Chen's research interest includes medical image, remote sensing image and vital sign signal processing.

On-Campus Interviews offer students a chance to conveniently interview for professional positions on campus.  Employers travel to our campus for the specific purpose of interviewing preselected students for currently open positions.  This is a great opportunity to interview with employers specifically interested in UMBC students and offers the advantage of a smaller applicant pool.  Interviews take place during the fall and spring. The logistics (viewing positions, applying, signing up for interview time slots, etc.) are all handled via UMBCworks.

Don't miss out on employers coming to UMBC to recruit YOU this fall! The following is a list of employers coming to conduct on-campus interviews with application deadlines in the next month.

On election day this November, some Marylanders will be voting on bond issues in addition to candidates and referenda. These ballot questions ask voters if their city or county should borrow money to fund particular projects, such as improvements to parks, schools and the Maryland Zoo in Baltimore.

At a time when government budgets are on everyone’s mind, Sheilah Kast of WYPR’s Maryland Morning asks UMBC political science professor Roy Meyers to shed light on these bond issues.

_Music of the Mind: Cliche Verre Photographs and Digital Imagery of Jaromir Stephany_, with an essay by Tom Beck, UMBC chief curator, has been published by the Albin O. Kuhn Library & Gallery. The life and work of Jaromir “Jerry” Stephany, an Associate Professor of Art from 1973 to 1999, are presented in a monograph for the first time. Stephany has the distinction of being one of only a few artists ever who devoted so much of his career to making cliché verre photographs. He learned the technique from his mentor Henry Holmes Smith (acolyte of Moholy-Nagy), and made such “cosmic” series as “Landscapes of Outer Space” and “Psychosis.” Later in his career, he scanned his negatives into a computer and added vibrant colors to the work, thereby achieving an emotional load much like the classical music that he enjoyed throughout his life. Stephany’s last body of work, “Dark Music,” captures the last movement of a life inspired by such music as Anton Bruckner’s Symphony No. 9 in D Minor. The book will be distributed by D.A.P. (Distributed Art Publishers).

UMBC political science professor Thomas F. Schaller appeared on television, radio and online media across Australia yesterday in coverage on the U.S. presidential election.

Schaller told “The World Today” and news.com.au that he expects the Democrats to hold the Senate and the Republicans to hold the House, by small margins, and President Obama to win the election by three or four points. Although one might expect high unemployment to hurt Obama’s chances, Schaller noted, many in the U.S. still blame former President Bush for current economic woes.

In a television interview on Australia World News, Schaller discussed Romney’s remarks about “the 47%,” which have dominated U.S. election news, and also the limited impact at this point of remaining undecided voters in key swing states. See the extended interview video for additional commentary.
