| Abstract: | 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. |
| Keywords: | relighting light-shadow transfer virtual lighting fusion virtual reality augmented reality |
