报告题目:Digital Material Appearance in Computer Graphics
内容摘要:In this talk, I will first briefly introduce the background of digital material appearance, in the context of computer graphics. I will then present two recent publications on casual appearance acquisition, which allows an average user to digitize not only the geometry of a daily object, but also its complex high-dimensional material appearance, using widely available consumer RGBD sensors. The first paper presents a material acquisition system that offers visual feedback to average users on-the-fly. Its key idea is to exploit the Kinect infra-red emitter/receiver, originally designed for depth computation, as an active hand-held reflectometer. The second paper considerably improves the material reconstruction quality using RGBD sensors, by using a joint optimization framework that alternates among solving for camera poses, materials, lighting and normals. I will conclude the talk with possible future directions for casual appearance acquisition.
