1. 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 ...

3. 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 ...

4. Characterization of Hyperspectral Imaging and Analysis via Microarray Printing of Dyes
Published: 2/22/2011
Authors: Matthew Lawrence Clarke, Maritoni Abatayo Litorja, David W Allen, Daniel Victor Samarov, Jeeseong Hwang
Abstract: The application of hyperspectral imaging requires rigorous characterization of the spatial and spectral imaging domains of the system. We present a microarray printing methodology for the testing of absorption or reflectance microscopy measurements. ...
