I pursued a full-time PhD in parallel with my full-time research position as a Principal Research Scientist at SRI International, and finished my PhD in 5 years (2010-2014).
Developed novel algorithms for image matching under disparate appearance (e.g. matching between image pairs like day-night, historic-current, painting-picture) using spectral correspondence. Developed purely geometric algorithms for geo-localization of street-level imagery using reference digital elevation data. Developed novel technology to match between aerial-oblique and street-view imagery of building facades with applications to image-based geo-localization.
