Outreach: ME Graduate Student Research Poster Session, March 2016

Each year,  potential graduate students (current undergraduate juniors and seniors) interested in Purdue’s ME graduate program come to campus for a visitation. This year, the students attended a 46-participant research poster session and had the ability to tour different ME research labs. I presented a poster, “High-speed 3D Optical Sensing and Applications,” at this session (PDF to poster below) detailing our […]

Webster, 2016; (Invited) ABSTRACT Modern hardware and algorithms, developed through several decades of research in multiple disciplines, are contributing toward the continuous advancement of 3D scanning technologies. Simply put, these technologies allow for […]

“Multiwavelength depth encoding method for 3D range geometry compression,” Appl. Opt., 2015

T. Bell and S. Zhang, “Multiwavelength depth encoding method for 3D range geometry compression”, Appl. Opt., 54(36), 10684-10961, 2015; doi: 10.1364/AO.54.010684 ABSTRACT This paper presents a novel method for representing three-dimensional (3D) range data within regular two-dimensional (2D) images using multiwavelength encoding. These 2D images can then be further compressed using traditional lossless (e.g., PNG) or lossy (e.g., JPEG) […]
