报告题目一: NPR effects for videogames
报 告 人：Mateu Sbert 教授（University of Girona, Spain）
I will present first in this talk our research group, Graphics and Imaging laboratory from the University of Girona, Spain, and its main lines of research, and after this I will introduce our latest research in non photorealistic rendering (NPR) applied to video games. The addition of post processing NPR effects to a video game would allow not only to comply with user preferences in rendering style, but also the creation of multiple gaming experiences out of the same game.
报告题目二: Content-Based Image Color Transfer
报 告 人：张晓鹏研究员（中科院自动化所）
I will talk about a novel color transfer method, content-based transfer of color patterns between images. Unlike previous methods that rely on image color statistics, we emphasis on high-level scene content analysis. Foreground subject areas and background scene layout are first automatically extracted from the scene. The semantic correspondences of the regions between source and target images are established. In the second step, the source image is re-colored in a novel optimization framework, which incorporates the extracted content information and the spatial distributions of the target color styles. A new progressive transfer scheme is proposed to integrate the advantages of both global and local transfer algorithms, as well as to avoid the over-segmentation artefact in the result. Our method can also be used to re-color video clips with spatially-varied color effects.
