摘要
基于图像的虚拟光影技术是直接改变图像场景中物体的光影效果或者估计场景光照,在光影维度对图像进行增强,并保留图像物体的视觉特征。从光影效果迁移、虚实光照融合两个方面盘点了虚拟光影技术的重要研究成果,展望了该领域关键技术的发展趋势。
The image-based virtual relighting(IBVR) is to directly modify the lighting effect of an object in the image or to estimate the lighting condition of the image. Unlike the traditional image processing technology, the images are processed in the domain of lighting, retaining the visual characteristics of an object. This paper reviews the important research advances of the IBVR in 2018, as well as its trend of development.
