Abstract: The color of materials derives from how they absorb and reflect different wavelengths of light. Color can be used to sensitively distinguish among objects of differing materials based on this selective reflectance. In hyperspectral imaging, fine material differentiation is achieved through the use of a dispersive element (such as a prism) to separate out images into hundreds of colors. Applications of airborne hyperspectral imaging include vegetation analysis to detect diseased vegetation and infestations, etc. It is also used widely in geology to map surface mineral deposits. I will talk both about the technology and applications of hyperspectral imaging, along with the challenges of working with this novel form of imaging.
As always, the talk will be at 7pm at the Pittsford Plaza Barnes and Noble in the Community Room. Coffee and cookies will be provided.
Our March and April talks are scheduled as well:
March 25: Dr. Duje Tadin (UofR): "What visual perception can tell us about the brain"
April 22: Dr. Eric Hittinger (RIT): "Everything You Wanted to Know About Renewable Energy"
