This paper presents a new light field capture system where the main design goal is low cost. To minimize cost we use an off-the-shelf flatbed scanner as the digitizing element. However, intrinsic properties of scanners can adversely affect resultant images. We will survey these properties and their effects in raw outputs. Image manipulation techniques will then be discussed so that proper light...

A real-time THz color scanner has the potential to further expand the application scope of THz spectral imaging based on its rapid image acquisition rate. We demonstrated three possible applications of a THz color scanner in the biomedical field: imaging of pharmaceutical tablets, human teeth, and human hair. The first application showed the scanner's potential in total inspection for rapid qua...

Automated MRI-derived measurements of in-vivo human brain volumes provide novel insights into normal and abnormal neuroanatomy, but little is known about measurement reliability. Here we assess the impact of image acquisition variables (scan session, MRI sequence, scanner upgrade, vendor and field strengths), FreeSurfer segmentation pre-processing variables (image averaging, B1 field inhomogene...

The cost of building a digitizing system for image-based rendering can be prohibitive. Furthermore, the physical size, weight, and complexity of these systems has, in effect, limited their use to small objects and indoor scenes. The primary motivations for this project is to reduce the acquisition cost of light-field capture devices and create a portable system suitable for acquiring outdoor sc...

A SCADA system for a single 3,000-mile-long strand of oil or gas pipeline may employ several thousand field devices to measure process parameters and operate equipment. Because of the vital tasks performed by these sensors and actuators, pipeline operators need accurate and timely information about their status and integrity. This paper describes a realtime scanner that provides situational awa...
