ALERT Researchers Awarded Best Paper at 2018 ICDSC Conference September 27, 2018
September 27, 2018
Dr. Octavia Camps (Project R4-A.1; Northeastern University), Dr. Richard Radke (Project R4-A.3; Rensselaer Polytechnic Institute), and their research team received the Best Paper Award at the 2018 International Conference on Distributed Smart Cameras (ICDSC) in Eindhoven, Netherlands on September 3-4, 2018.
The paper, titled “Correlating Belongings with Passengers in a Simulated Airport Security Checkpoint,” is co-authored by Ashraful Islam, Yuexi Zhang, Dong Yin, Octavia Camps and Richard Radke. The research for this paper was done using data collected for CLASP (Correlating Luggage and Specific Passengers) project at ALERT’s Video Analytics Lab located at the Kostas Research Institute for Homeland Security at Northeastern University.
According to the paper’s abstract, “Automatic algorithms for tracking and associating passengers and their divested objects at an airport security screening checkpoint would have great potential for improving checkpoint efficiency, including flow analysis, theft detection, line-of-sight maintenance, and risk-based screening. In this paper, we present algorithms for these tracking and association problems and demonstrate their effectiveness in a full-scale physical simulation of an airport security screening checkpoint. Our algorithms leverage both hand-crafted and deep-learning-based approaches for passenger and bin tracking, and are able to accurately track and associate objects through a ceiling-mounted multi-camera array. We validate our algorithm on ground-truthed datasets collected at the simulated checkpoint that reflect natural passenger behavior, achieving high rates of passenger/object/transfer event detection while maintaining low false alarm and mismatch rates.”

ALERT REUs Deliver Final Presentations September 27, 2018
September 27, 2018
Summer is a time for soaking up the sun, but for seven ambitious undergraduate students who participated in ALERT’s 10-week long Research Experiences for Undergraduates (REU) Program, this summer was dedicated to ALERT research! At Northeastern University (NU), Anthony Englert (University of Massachusetts Amherst) and Samuel Kebadu (George Mason University) worked with Professor Carey Rappaport (Projects R3-A.2, & R3-A.3); and Alexis Costales (Washington University in St. Louis), Diego Rojas (NU), and Joe Von Holten (NU) worked with Professor Jose Martinez Lorenzo (Projects R3-B.1 & R3-B.2). At the University of Puerto Rico Mayagüez (UPRM), UPRM undergraduates, Samuel J. García-León and Roberto A. Rivera-De Jesús worked with Professor Samuel Hernandez (Project R3-C). The ALERT REU Program at NU collaborates with other REU programs in NU’s College of Engineering to build a cohort of students who jointly attend professional development meetings and program activities.
On August 9th, ALERT and Gordon-CenSSIS REUs based at NU delivered final presentations to friends, family, mentors, and professors on their project’s mission, their research contributions, and the knowledge and skills they gained from the program. The event kicked off at 9:00am with opening remarks from NU Professor David Kaeli (Electrical and Computer Engineering). A poster session was held at noon, where REUs shared posters they created, detailing their research contributions. During the session, faculty and mentors talked to each student about their work and judged them on three different categories: overall poster organization, research process presented clearly on poster, and oral presentation skills.
The event concluded with an award ceremony and closing remarks from Melanie Smith, REU Program Manager. Five students won an award for their posters including ALERT REUs, Anthony Englert and Sam Kebadu for their poster “Experimental Validation of a Multi-Static Imaging System for Concealed Threat Detection.” According to Professor Rappaport, “Anthony and Sam embraced the problem [focusing mm-waves for Advanced Imaging Technology] and were enthusiastically dedicated to solving it.”

ALERT Leads Trace Detection Seminar for Industrial Partner September 27, 2018
September 27, 2018
ALERT Thrust R2 Lead, Dr. Steve Beaudoin (Purdue University) led a seminar on Trace Detection at Rapiscan Systems, an OSI Systems Company, in Andover, Massachusetts on August 17, 2018. Rapiscan Systems, an ALERT Industrial Partner, specializes in providing state-of-the-art products, solutions, and services to meet the threat detection needs at airports, border crossings, railway stations, government and military installations, and high-risk facilities around the world.
Under the ALERT Industrial Partnership model, Industrial Partners can select one or more ways to allocate their membership fees. One of those options is a full-day seminar on a topic of the Industrial Partner’s choice and relevant to one of ALERT’s four research thrusts.
Dr. Beaudoin spent the morning with about 15-20 Rapiscan employees, interns, and co-op students from several disciplines. During this time, he gave a 2-hour (10:00am-12:00pm) lecture style presentation on Trace Detection covering three topics of interest: particulate explosives, compound explosives, and the TESSA Project – Contact Sampling Study. Participants had the opportunity to ask questions during the presentation, and after lunch, there were several more hours of Q&A and discussion (ending at 4:00pm). Several collaboration opportunities were discussed throughout the day, as well as several ways in which the two organizations can support one another’s work.
The feedback throughout the day, from several Rapiscan employees, was very positive and was followed by a request for more seminars in the future. Dr. Beaudoin’s contact sampling project report and seminar presentation was disseminated to the Rapiscan team as a resource.
According to Stefan Lukow, Ph.D., Director of Research and Development at Rapiscan Systems, “The seminar last Friday was very well received by many members of my R&D group as well as the greater engineering team. Throughout Steve’s presentation, there were many discussions and also ideas spurred for potential collaboration or suggestions for future work to be done by either side. It was informative and took the tone of a discussion rather than a lecture. Following the presentations, Steve made himself available for additional discussion with the engineering team for more in-depth discussions and several took him up on this offer. Overall, it was greatly beneficial to have Steve present his work and that of the ALERT center. I hope for more opportunities in the near future.”

2018 DHS COE Summit Facilitates Collaboration and Advances DHS Mission July 31, 2018
ALERT, along with other current and emeritus DHS Centers of Excellence (COEs), hosted the 2018 Centers of Excellence Summit in Arlington, Virginia on May 30-31, 2018. The event focused on the topic of “University Research and Development to Protect the Homeland.” The DHS COE Summit provided the Centers of Excellence an opportunity to showcase their innovative solutions to homeland security challenges and facilitate collaboration across homeland security enterprise leadership and component end-users and industry participants. According to ALERT Center Director, Michael B. Silevitch,
“One of the most valuable aspects of the Summit was the teamwork needed to pull it together. It required a concerted effort by all of the COEs to organize and orchestrate the event. Going forward, this teamwork will lead to meaningful cross-center collaboration.”
The agenda for the two-day long summit was launched with a keynote address from Christopher C. Krebs, Senior Official Performing the Duties of Under Secretary, National Protection and Programs Directorate (NPPD) and included talks by various security administrators, panel discussions, student posters, and a technology showcase.
Director Silevitch moderated a panel focused on “Transportation and Critical Infrastructure” on the first day of the summit. Panelists Carl Crawford, Eva Lee, David Nicol, and Detlof VonWinterfeldt addressed four questions related to this topic:
- What are some of the grand challenges that need to be addressed to enable the next generation of Homeland Security transportation and critical infrastructure solutions?
- What research needs to be done in order to address these challenges?
- How can the research outcomes be effectively transitioned to the field?
- What metrics can be used to enable a cost-benefit analysis of the research/transition impact?
ALERT’s Transition Team made connections with end users at the technology showcase and featured some of ALERT’s latest solutions in multi-view air cargo CT scanners, effective personnel screening, video tracking at the airport security checkpoint, and K9 explosives training aids.
COEs excel in advancing the state of the art thanks in large part to their student researchers. To acknowledge this, the summit provided students with the opportunity to present their work to attendees. Katherine Graham, one of ALERT’s talented undergraduate researchers, took home the Best Poster Award for her work on “Compressive Reflector Antennas for High-Sensing Capacity Imaging Applications.” These antenna designs provide a less complex and lower cost solution for high-sensing capacity millimeter wave imaging systems. Millimeter wave imaging systems have the potential for use in several near-field imaging applications such as security screening, non-destructive testing, autonomous driving, and biotechnology. The abstracts for the COE Summit student posters are available for download on the COE Summit 2018 website.
The summit provided an all-hands-on-deck approach to addressing homeland security challenges by bringing together some of the nation’s best academic, public, and private sector leaders to discuss strategies for advancing the mission of the Department of Homeland Security. ALERT looks forward to the next DHS COE Summit, and hopes you will join us there!

ALERT Research Highlight: The Largest and Most Systematic Re-id Benchmark to Date May 30, 2018
ALERT researchers Professor Octavia Camps (Northeastern University, Project R4-A.1) and Professor Rich Radke (Rensselaer Polytechnic Institute, Project R4-A.3) and their students, Srikrishna Karanam, Mengran Gou, Ziyan Wu, and Angels Rates-Borras, were recently published in the Institute of Electrical and Electronics Engineers’ (IEEE) monthly journal, Transactions on Pattern Analysis and Machine Intelligence (download here). The paper, “A Systematic Evaluation and Benchmark for Person Re-Identification: Features, Metrics, and Datasets,” provides an extensive review and performance evaluation of existing person re-identification algorithms.
Person identification, or re-id, matches observations of individuals across multiple camera views in a network of surveillance cameras, and represents a critical task in most surveillance and security applications. For example, a police officer may want to automatically follow a person of interest tagged at a check-in counter through the branching concourses of an airport. The research team’s recent review and evaluation of re-id algorithms helps characterize what re-id algorithms are currently capable of accomplishing, as well as what is missing and what is possible in the future. In this paper, the researchers discuss insights gained from their study, as well as put forth research directions and recommendations for re-id researchers that would help develop better algorithms in the future. Both Professor Camps and Professor Radke are involved with ALERT’s Research Thrust 4, which focuses on video surveillance and the analysis of video data with novel algorithms. This publication was the result of years of research and collaboration between their respective labs.
The fundamental re-id problem is to compare a person of interest as seen in a “probe” camera view to a “gallery” of candidates captured from a camera that does not overlap with the probe camera. If a true match to the probe exists in the gallery, it should have a high matching score, or rank, compared to incorrect candidates. Since the body of research in re-id is increasing, researchers can begin to draw conclusions about the best combinations of algorithmic subcomponents. In this paper, the researchers present a careful, fair, and systematic evaluation of feature extraction, metric learning, and multi-shot ranking algorithms proposed for re-id on a wide variety of benchmark datasets. Their general evaluation framework considers hundreds of combinations of (1) feature extraction and metric learning algorithms for single-shot datasets and (2) feature extraction, metric learning, and multi-shot ranking algorithms for multi-shot datasets.
The research team evaluated 276 algorithm combinations on 10 single-shot re-id datasets and 646 algorithm combinations on 7 multi-shot re-id datasets, making the proposed study the largest and most systematic re-id benchmark to date. Approaches were evaluated using 17 datasets that mimic real world settings, including the ALERT Airport Re-Identification Dataset. As part of the evaluation, the researchers built a public code library with an easy-to-use input/output code structure and uniform algorithm parameters that includes 11 contemporary feature extraction and 22 metric learning and ranking algorithms. Both the code library and the complete benchmark results are publicly available for community use.
