11. An Analysis of the Probability Distribution of Spectral Angle and Euclidean Distance in Hyperspectral Remote Sensing Using Microspectroscopy
Published: 5/18/2013
Authors: Ronald Resmini, Christopher Deloye, David W Allen
Abstract: Determining the probability distribution of hyperspectral imagery (HSI) data and of the results of algorithms applied to those data, is critical to understanding algorithm performance and for establishing performance metrics such as probability o ...

12. Calibration and validation scheme for in vivo spectroscopic imaging of tissue oxygenation
Published: 8/9/2012
Authors: Maritoni Abatayo Litorja, Robert C. Chang, Jeeseong Hwang, David W Allen
Abstract: The determination of the level of oxygenation in optically accessible tissues using multispectral or hyperspectral imaging (HSI ) of oxy- and deoxyhemoglobin has special appeal in clinical work due to its non-invasiveness, ease of use and capability ...

13. The evaluation of hyperspectral imaging for the detection of person-borne threat objects over the 400 nm to 1700 nm spectral region
Published: 5/10/2012
Authors: Catherine C Cooksey, Jorge Enrique Neira, David W Allen
Abstract: The detection of person-borne threat objects, such as improvised explosive devices, at a safe distance is an ongoing challenge. While much attention has been given to other parts of the electromagnetic spectrum, very little is known about what potent ...

14. Algorithm Validation Using Multicolor Phantoms
Published: 5/9/2012
Authors: Daniel Victor Samarov, Matthew Lawrence Clarke, Ji Y. Lee, David W Allen, Maritoni Abatayo Litorja, Jeeseong Hwang
Abstract: We present a framework for hyperspectral image (HSI) analysis validation, specifically abundance fraction estimation based on HSI measurements of water soluble dye mixtures printed on microarray chips. In our work we focus on the performance of tw ...

15. Designing Microarrays Phantoms for Hyperspectral Imaging Validation
Published: 5/9/2012
Authors: Matthew Lawrence Clarke, Ji Y. Lee, Daniel Victor Samarov, David W Allen, Maritoni Abatayo Litorja, Ralph Nossal, Jeeseong Hwang
Abstract: The simple design of custom-tailored microarrays for the characterization of hyperspectral imaging systems and analysis methods for biologically relevant samples. Individual and mixtures of dyes were printed on microscope slides and imaged by a hyper ...

16. Hyperspectral Image Projector Applications
Published: 2/15/2012
Authors: Joseph Paul Rice, Steven W Brown, David W Allen, Howard W Yoon, Maritoni Abatayo Litorja, Jeeseong Hwang
Abstract: For the past several years NIST has been developing, along with several collaborators, a Hyperspectral Image Projector (HIP). This scene projector produces high-resolution programmable spectra and projects them into dynamic two-dimensional images ...

17. Hyperspectral Imaging of Ischemic Wounds
Published: 2/1/2012
Author: David W Allen
Abstract: Optical imaging has the potential to achieve high spatial resolution and high functional sensitivity in wound assessment. However, clinical acceptance of many optical imaging devices is hampered by poor reproducibility, low accuracy, and lack of ...

18. Validating the LASSO Algorithm by Unmixing Spectral Signatures in Multicolor Phantoms
Published: 2/1/2012
Authors: Daniel Victor Samarov, Matthew Lawrence Clarke, Ji Y. Lee, David W Allen, Maritoni Abatayo Litorja, Jeeseong Hwang
Abstract: As hyperspectral imaging (HSI) sees increased implementation into the biological and medical fields it becomes increasingly important that the algorithms being used to analyze the corresponding output be validated. While certainly important under any ...

19. Hyperspectral Imaging and Analysis of Single Erythrocytes
Published: 8/12/2011
Authors: Ji Y. Lee, Matthew Lawrence Clarke, Fuyuki Tokumasu, John F. Lesoine, David W Allen, Robert C. Chang, Maritoni Abatayo Litorja, Jeeseong Hwang
Abstract: We report a hyperspectral imaging and analysis technique to resolve unique physico-chemical characteristics of subcellular substances in single erythrocytes. We constructed a microscope system installed with a spectral light engine capable of contr ...

20. Investigation of the potential use of hyperspectral imaging for stand-off detection of person-borne IEDs
Published: 5/23/2011
Authors: Catherine C Cooksey, David W Allen
Abstract: Advances in hyperspectral sensors and algorithms in numerous fields of research have opened up new possibilities for its use in the detection of person-borne IEDs. While portions of the electromagnetic spectrum, such as the x-ray and terahertz regio ...
