Teaching for Spring Semester 2011

In Spring 2011, I am teaching 2 classes. Computational Photography (CS 4475 HP/ 8803 PHO) This class explores perceptual and technical aspects of pictures, and more precisely the capture and depiction of reality on a 2D medium. The scientific, perceptual, and artistic principles behind image-making will be emphasized. Topics include the relationship between pictorial techniques […]

Paper ISMAR 2009: "Augmenting Aerial Earth Maps with Dynamic Information"

Augmenting Aerial Earth Maps with Dynamic Information [bibtex file=IrfanEssaWS.bib key=2009-Kim-AAEMWDI] Abstract We introduce methods for augmenting aerial visualizations of Earth (from tools such as Google Earth or Microsoft Virtual Earth) with dynamic information obtained from videos. Our goal is to make Augmented Earth Maps that visualize the live broadcast of dynamic sceneries within a city. […]
