The goal of facial expression analysis is to create systems that can automatically analyze and recognize facial feature changes and facial motion due to facial expressions from visual information. This has been an active research topic for several years and has attracted the interest of many computer vision researchers and behavioral scientists, with applications in behavioral science, security, animation, and human-computer interaction. In this talk, I will briefly describe the components of a facial expression analysis system and review some previous work. Then I will talk about my work, View-Invariant Expression Analysis using Analytic Shape Manifolds and Structure-Preserving Sparse Decomposition for Facial Expression Analysis.

===Rendering massive virtual world using Clipmaps===

Real time rendering of a massive virtual world requires efficient management of textures, geometric structures, and a variety of visual effects. Despite the recent improvements of the Graphics Processing Units (GPU), the currently available memory space and computation power is still not enough to store and process textures and geometries that are used to represent a high-quality virtual world. One way to overcome this problem is use Clipmap, which is a hardware accelerated approach that manages levels of detail (LOD) for objects, textures, and effects used to render a virtual world.
