Iphone-Based Image Refocusing, Katie Jeong, Daniel Niu

Electrical and Systems Engineering Capstone Design Projects

In this project, we show that we can change the focus of a picture after we take it by using real optical physics instead of fake software blur. Modern phones try to create “portrait mode” effects, but those results are often not physically correct. Our approach uses multiple photos taken from slightly different positions to figure out the directions that light rays came from in the scene.

To collect the photos, we move an iPhone sideways on a slider in small, precise steps. Since we know exactly how far the phone moved for each picture, we can track how objects …

Purpose: Radiation-induced heart damage is a significant concern in the treatment of non-small cell lung cancer (NSCLC) that can have debilitating or life-threatening consequences. Current strategies focus on minimizing heart exposure, but individual susceptibility varies. Existing evidence also suggests that a uniform "one-size-fits-all" dosimetric constraint for the heart may not be optimal for all patients.

Methods and materials: We developed a prospective study using Bayesian continuous learning and adaptation to develop a framework for personalized adaptive radiation treatment (PART) to reduce cardiovascular adverse events among patients with locally advanced NSCLC. The trial includes a Bayesian personalized risk prediction model to …

This relationship is analyzed using the gravity model of trade to perform a regression analysis of total trade levels from 2000 to 2018. The results of this study did not support the idea that hosting the Olympic Games impacts total trade; although, they did show a strong and permanent positive relationship between unsuccessfully bidding to host the Olympic Games and total international trade. These findings highlight the benefits of the Olympic bidding and candidature process as a policy …

Examining The Intersectional And Structural Issues Of Routine Healthcare Utilization And Access Inequities For Lgb People With Chronic Diseases, Shiya Cao, Mehreen Mirza, Sophia Silovsky, Nicole Tresvalles, Lucia Qin, Sarah Susnea

Statistical and Data Sciences: Faculty Publications

In the United States, although the gaps in health insurance coverage by sexual orientation have been closing since the implementation of the Affordable Care Act and legalization of same-sex marriage, the LGB group (i.e., lesbian, gay, bisexual) continues to report healthcare utilization and access inequities such as more delayed or unmet care. The extant research has often examined healthcare utilization and access inequities due to affordability (e.g., out-of-pocket costs). However, healthcare utilization and access inequities are only partially explained by cost reasons; there are non-cost reasons that have not been adequately empirically examined. The present study innovatively includes discrimination structural …

Adaptive Image Acquisition Algorithms For Resource-Constrained Single-Photon Cameras, Yeganeh Jalalpour, Wu-Chi Feng

Computer Science Faculty Publications and Presentations

Emerging single-photon camera (SPC) technologies have unique challenges in data acquisition and processing. Unlike conventional sensors that produce a single 8- to 16-bit brightness value per pixel, SPCs record photon arrivals with many more samples per pixel, using high floating-point precision for each photon collected. This means that they must handle potentially millions of timestamps, especially at higher spatial resolutions and in the presence of ambient light, creating bottlenecks within the pixel circuitry. To address these challenges associated with SPCs, this paper proposes adaptive algorithms designed to efficiently distribute hardware resources among groups of pixels. By selectively subsampling the data …

Folia Medica Indonesiana

The incidence of type 2 diabetes mellitus (T2DM) is influenced by both unmodifiable factors, such as age, family history, education, and employment status, as well as modifiable factors, including obesity, diet, physical activity, and smoking habits. Researchers have recognized the necessity of research on risk factors for T2DM across various regions. However, the findings have been inconsistent. The absence of research on risk factors for T2DM in some regions has necessitated the conduct of studies in these areas, particularly in primary health care facilities such as Community Health Centers (\textit{Puskesmas}). This study aims to control the risk factors that contribute …

The Formation And Dynamics Of Colonial “Lived Spaces” : Urban Space And Society In Colonial Hanoi, 1883–1916, Nam Khanh Hoang '25

Student Research

This study examines the nuanced experiences and perceptions of urban space among different social groups in colonial Hanoi in the late nineteenth and early twentieth centuries by analyzing the French colonial agendas, as reflected through modern urban planning and practices, and its reception among the colonial urban inhabitants, as suggested through their responses to the Statue of Liberty—a colonial urban monument. While existing scholarship has often framed colonial cities as stages for consolidating imperial power, introducing Western ideals of modernity, and forming systems of oppression and exploitation against colonial subjects, it has often overlooked the perceptions and experiences of colonial …

Hint-Guided Video Frame Interpolation For Video Compression, Pan Tan, Wu-Chi Feng

Computer Science Faculty Publications and Presentations

Traditional video compression continues to advance, but the gainsin efficiency are diminishing and come at the cost of higher compu-tational complexity. Despite achieving competitive rate-distortionresults, current neural video codecs (NVCs) generally lack sup-port for a wide range of quality levels, often requiring multiplemodels to achieve flexible rate control, which increases both train-ing cost and deployment complexity. To address the limitations ofboth traditional codecs and current NVCs, we propose a hybridvideo compression framework that integrates traditional codecswith hint-guided video frame interpolation (VFI), a learning-basedtechnique for synthesizing intermediate frames. By using decodedreference frames and leveraging compressed-domain hints to guideinterpolation, our method improves …

Elm: The Case Of Experiential Programming, Matthew Miller, Lynette Campogiani

Faculty and Staff Publications & Presentations

Experiential Programs (EPs) provide immersive, destination-focused experiences within luxury resort settings. However, research has yet to apply the elaboration likelihood model (ELM) to examine how guests evaluate their experiences with EPs, particularly within luxury tourism or resort contexts. Using the ELM framework, this study examined how the experience of luxury resort EPs influences guests’ revisit intentions. Guests’ experiences were categorized into central and peripheral processing cues and qualitative interview responses were analyzed. The findings indicate that elements such as ambient music and scenic views associated with peripheral processing had a significantly stronger positive impact on guests’ intentions to return than …

Analyzing Human–Robot Collaboration Failures In State-Of-Art Generative Visuomotor Models, Grant Henderson, Miguel Mateo Osorio Vela, Vidhi Mudaliar, Amanuel Ergogo, Zhao Han

Bellini College REU Symposium (BCREUS)

As generative visuomotor models become increasingly capable of representing large-scale robotic skills, they are beginning to transition from controlled laboratory environments into shared human-robot workspaces. While these models enable competent manipulation, their opaque, black-box decision-making processes introduce coordination challenges that can negatively impact safety, efficiency, and trust during collaboration. In safety-critical tasks such as medication dispensing, successful teamwork depends not only on physical capability but also on timing, predictability, and mutual awareness.

This project investigates how two state-of-the-art generative visuomotor policies, an Action-Chunking Transformer (ACT) and a Vision-Action Diffusion policy, perform in a real-world collaborative medication-dispensing task. We compare these …
