Researcher Highlight: Henry Medeiros on CLASP June 29, 2020

For users without YouTube access: Henry Medeiros on CLASP 

The Correlating Luggage and Specific Passengers (CLASP) Task Order is a research initiative to develop technology to automatically track passengers and their divested items at the checkpoint using video analytics. This task order, funded by DHS Science and Technology has brought together research teams from several universities including Boston University, Northeastern University, Rensselaer Polytechnic Institute, and Marquette University.

Henry Medeiros, Assistant Professor of Electrical and Computer Engineering at Marquette University, is working on CLASP research that is specifically focused on creating algorithms that track passengers and their baggage items throughout the entire checkpoint. To develop this technology, Henry’s research team uses machine learning and algorithms developed to identify and detect various scenarios that may occur at a checkpoint.

The ultimate goal of Henry’s research team is to simplify the check-in process with a system that would be able to determine that each passenger is following the required security procedures at airport checkpoints. In our latest ALERT video, Henry discusses his work with CLASP and how this research is changing the airport security landscape.

Watch our latest video, Meet the ALERT Students!  Hear from Annette Colón Mercado (Project R3-C), Muhammad Usman Ghani (Project R4-C1), and Meng Zheng (Project R4-A3) as they discuss their projects and the importance of ALERT research while participating in the ALERT Industrial Advisory Board Meeting last fall.

The annual Industrial Advisory Board (IAB) Meeting provides students with opportunities to present their work during the student poster session, which allows for networking with industrial members as well as local, state, and federal government representatives. Annette has participated in the IAB meeting for two years and she believes that ALERT research is important to her because, “We are working to make our nation a safer and a more secure place by doing the research we do and by implementing these detection systems for DHS current problems.”

ALERT students are engaged in many events designed to highlight their research accomplishments including the Annual Student Pipeline Industry Roundtable Event (ASPIRE) and the ALERT Technology Showcase.

ASPIRE is held annually each spring at Northeastern University in Boston to support students looking for internships, co-op opportunities and full-time jobs. Students have the opportunity to connect with industrial and government partners through one-on-one meetings to discuss their research, practice “elevator pitches” and discuss employment opportunities

ALERT’s Technology Showcase focuses on the transition of ALERT’s work through presentations, posters, and technology demonstrations of the Center’s research and tools. Students from each project are invited to present their project during the poster session which allows them to connect with faculty, industrial partners, and government representatives throughout the Showcase.

ALERT Researchers, Dr. Jimmie Oxley and Dr. Otto Gregory featured in the Press December 18, 2019

ALERT Researcher and URI Professor, Dr. Jimmie Oxley, was recently featured on CBS News discussing TSA projects aimed at improving the security screening process for travelers. The story details new technology being developed as part of ALERT research at URI such as the desensitizing agent known as SCHMOO (Safe Control of Hazard Materials or Others Onsite) recently developed by Dr. Oxley’s team.  SCHMOO is a unique gel that can be applied to hazardous materials to neutralize them and allow for safe removal and transportation for later analysis.

The CBS article also describes the “digital dog nose” being developed by ALERT Researcher and URI Professor, Otto Gregory with the goal of detecting explosives as well as or better than a bomb-sniffing dog.  Dr. Gregory is featured in an additional story on ABC News  during with he describes one benefit of the digital dog nose as being available around the clock, thereby not requiring breaks and reinforcement which is necessary for the dogs.

Both news items also describe the “Innovation Checkpoint” at McCarran International Airport in Las Vegas which is a testing space for TSA technologies such as ID readers that will scan licenses to validate identification and flight information without the need to show a boarding pass at the security checkpoint.


Dr. Gregory’s related journal article titled, “Orthogonal Sensors for the Trace Detection of Explosives” appeared in IEEE Sensors in October 2019 and was the subject of a lead story in the IEEE Spectrum.

ALERT Technology Showcase: Inspiring Innovation October 31, 2019

For users without YouTube access: ALERT Technology Showcase: Inspiring Innovation

This past May, the ALERT Center of Excellence held its first Technology Showcase at Northeastern University. The showcase featured presentations, posters, and technology demonstrations of the Center’s research and tools, highlighting ALERT’s partnerships with industry and government.

In our latest ALERT video, ALERT Technology Showcase: Inspiring Innovation, attendees discuss the importance of bringing researchers from various backgrounds together to share their work and receive diverse viewpoints on their technical approach. Highlighting how this type of a showcase is rare, Astrophysics, Inc. CEO, François Zayek thought it was a great way to encourage researchers to step back from their interests and learn about new technology.

Not only did researchers like ALERT Video Analytics and Signature Analysis Lead, David Castañón, find sharing their work and innovative technologies amongst peers helpful, they also found the exposure to industry and government stakeholders provided a different, yet significant perspective.

“Companies get to see you, and they’re not always available while you’re doing research at a University. It’s good to get feedback from people from different viewpoints in the company and the government. They say, ‘well this is interesting,’ and this may be useful in a context that I hadn’t thought of.”

– David Castañón, ALERT Video Analytics and Signature Analysis Lead and Professor of Electrical and Computer Engineering at Boston University.

“ADSA in Three Words” (Video) January 29, 2018

What began as a relatively small workshop (approximately 30 attendees) on the campus of Northeastern University (Boston, MA) in 2009, has evolved into an interactive biannual conference series with over 150 participants regularly. Viewed by participants as a “forum which brings together many different communities with a common goal of solving security challenges,” (ADSA17 participant quote), the ADSA (Advanced Development for Security Applications) Workshop series intends to facilitate collaboration and innovation between these communities.

At the last ADSA workshop (ADSA17 Workshop), ALERT asked several participants to sum up the biannual event in only three words. See what government, industry, and research participants had to say in “ADSA in Three Words.”

ALERT Launches Video Analytics Lab at Kostas Research Institute May 30, 2017

A Better Testing Facility for Solving Real World Problems

Northeastern University’s George J. Kostas Research Institute for Homeland Security is now home to ALERT’s new Video Analytics Laboratory. Providing secure access, 1225 sq. feet of open space, controlled lighting conditions, and a fully networked and flexible camera grid, ALERT can better investigate and develop video and sensor technologies to address the needs of the Homeland Security Enterprise.

Using Video Technologies to Improve Passenger Experience

The first research project to leverage the lab is entitled Research and Development of Systems for Tracking Passengers and Divested Items at the Checkpoint. Supported by the DHS Science and Technology Directorate through the DHS Office of University Programs, this project is known by the acronym CLASP (Correlating Luggage and Specific Passengers) and leverages the technical expertise of ALERT research teams from Boston University, Marquette University, Northeastern University, Purdue University, and Rensselaer Polytechnic Institute. These teams will work towards developing an automated system capable of tracking passengers and divested items at airport security checkpoints.

CLASP will primarily focus on using video technologies to assist the Transportation Security Administration (TSA) in effectively identifying security incidents like theft of items, or bags left behind at the checkpoint. By automating and improving the technologies associated with these objectives, ALERT hopes to improve rates of detection and at the same time improve the passenger experience.

CLASP was the result of DHS’s interest in initial work done by ALERT Project Investigator Richard Radke’s lab. A video of their work can be seen below:

(Z. Wu and R.J. Radke, Real-Time Airport Security Checkpoint Surveillance Using a Camera Network. Workshop on Camera Networks and Wide Area Scene Analysis, in conjunction with CVPR 2011, June 2011.).

Government & Industry Partners Make the Difference

In order to deliver the system outlined in CLASP, the researchers working on the project require access to video data displaying real-world checkpoint security situations. Actual airport security video is generally restricted, so ALERT partnered with Massport, the Transportation Security Administration at Boston Logan International Airport, and industrial partners such as Rapiscan Systems to create an accurate representation of an airport security checkpoint in the ALERT Video Analytics Laboratory. This full-scale, mock airport security checkpoint uses the same hardware and design specifications currently used by the TSA at airports such as Logan, and gives ALERT a space to generate usable video data for this project and hopefully to the video analytics research community as a whole.

CLASP is just the beginning of work that can be done in this new laboratory and ALERT is hoping to leverage it for additional homeland security-related projects going forward. If you are interested in partnering with ALERT on future projects, please connect with us via email at [email protected].
