ABSTRACT:

Texture analysis and synthesis has been studied extensively by many vision
and graphics researchers. A very useful concept in texture analysis is
texton or the basic element of a texture image. However, it remains
unclear how to define a texton despite the fact that Julesz proposed the
term "texton" more than twenty years ago. In this talk, I will propose a
two-level statistical model with textons and their distribution for
texture analysis and synthesis, with the emphasis on how to define textons
computationally. Specifically, I will present our recent work on searching
for 2D textons in patch-based texture synthesis (ACM ToG, July 2001), 3D
textons in Bi-directional texture function (BTF) synthesis (Siggraph'2002)
and 1D motion textons in motion texture synthesis (Siggraph'2002).

Harry Shum received his Ph.D. in robotics from the School of Computer
Science, Carnegie Mellon University in 1996. He worked as a researcher for
three years in the vision technology group at Microsoft Research Redmond.
In 1999, he moved to Microsoft Research Asia where he is currently a
senior researcher and the assistant managing director. His research
interests include computer vision, computer graphics, human computer
interaction, pattern recognition, statistical learning and robotics. He is
the General Co-Chair of Ninth International Conference on Computer Vision
