Knobel R, Guenther B, Rice H
Biol Res Nurs . 2011 May; 13(3):274-82. PMID: 21586499
Introduction: Infrared thermal imaging, or thermography, is a technique used to measure body surface temperature in the study of thermoregulation. Researchers are beginning to use this novel methodology to study...

Fang J, Hao Q, Brady D, Guenther B, Hsu K
Opt Express . 2009 Jun; 15(6):3271-84. PMID: 19532568
This paper presents a novel biometric system for real-time walker recognition using a pyroelectric infrared sensor, a Fresnel lens array and signal processing based on the linear regression of sensor...

Fang J, Hao Q, Brady D, Guenther B, Hsu K
Opt Express . 2009 Jun; 14(15):6643-58. PMID: 19516845
This paper proposes a real-time human identification system using a pyroelectric infrared (PIR) detector array and hidden Markov models (HMMs). A PIR detector array with masked Fresnel lens arrays is...

Fang J, Hao Q, Brady D, Shankar M, Guenther B, Pitsianis N, et al.
Opt Express . 2009 Jun; 14(2):609-24. PMID: 19503378
This paper presents a design and development of a low power consumption, and low cost, human identification system using a pyroelectric infrared (PIR) sensor whose visibility is modulated by a...

Kittle D, Holshouser B, Slater J, Guenther B, Pitsianis N, Pearlstein R
Med Phys . 2009 Jan; 35(12):5708-12. PMID: 19175128
Three dimensional grid phantoms offer a number of advantages for measuring imaging related spatial inaccuracies for image guided surgery and radiotherapy. The authors examined the use of rapid prototyping technology...

Burchett J, Shankar M, Ben Hamza A, Guenther B, Pitsianis N, Brady D
Appl Opt . 2006 Apr; 45(13):3031-7. PMID: 16639451
We use pyroelectric detectors that are differential in nature to detect motion in humans by their heat emissions. Coded Fresnel lens arrays create boundaries that help to localize humans in...

Zheng Y, Brady D, Sullivan M, Guenther B
Appl Opt . 2005 Jul; 44(20):4306-14. PMID: 16045218
With the objective of monitoring motion within a room, we segment the two-dimensional (2D) floor space into discrete cells and encode each cell with a binary code word generated by...
