Work on my dissertation "Unsupervised hyperspectral target detection".

 

   
May, 2007 to Dec, 2007

ORISE Fellowship/ Intern in Division of Image and Applied Mathematics (DIAM), Food and Drug Administration (FDA)

Research:
•Develop estimation techniques for virtual dimensionality of hyperspectral image data according to different targets/pixels of interests.

•Study the variance estimation techniques for reader agreement statistics under the scope of multiple readers, multiple cases (MRMC) analysis.

•Improve the accuracy of traditional ROC analysis on the evaluation of medical devices or other detection problems in different applications.

•Perform Monte Carlo simulations on model observer experiments via cluster computing environment.

Agreement statistics: Evaluate several agreement measures and their variance estimates when the quantification scheme and between-reader correlation are changing. The study can be used in the evaluation of discriminators and classifiers in remote sensed data analysis.
