Interactive Image Manipulations: Color, Size and Structure

(Coffee and cookies at 10:30 AM)

Image manipulation is as old as the invention of photography. Traditionally, changing the color or size of an image required an expert in the field. Today, computers have made such tasks more accessible, but they are still labor intensive. In this talk I will present some new algorithms and tools that simplify image manipulations so they become natural for any user. These tools rely on the computational power and information processing abilities of modern computers and networks, to create simple user interfaces for image manipulations. I will demonstrate how changing colors can be transformed into navigation through inspirational examples, how image resizing can preserve important image content and illustrate a tool that can fabricate photorealistic images from users' sketches.

Ariel Shamir is an associate professor at the Interdisciplinary Center in Herzliya, Israel. He received his Ph.D. in computer science from the Hebrew University in Jerusalem in 2000. He has spent two years at the computational visualization center at the University of Texas in Austin, and in 2007 held the position of a visiting scientist at Mitsubishi Electric Research Labs in Cambridge MA. During the years he has been involved in consulting for a number of places such as Lawrence Livermore National Laboratory, Walt Disney Research, and a number of high-tech companies in Israel. He also co-authored several patents. His research interests include geometric modeling, image processing, computer graphics, visualization, and machine learning. He is a member of the ACM SIGGRAPH, IEEE Computer, and Eurographics associations.
