Abstract
In mixed-reality environments it is essential to integrate virtual objects seamlessly into a real scene. Virtual objects should have similar appearances to those of real objects captured by a video camera. This is useful for many real-life application scenarios, including product advertising and visualization, edutainment systems or for enhancing cultural heritage sites.Typical problems in this domain are to match the current ‘color mood’ of the video camera scene with the colors of virtual (rendered) objects. The color mood depends on the global illumination conditions as well as the hue, saturation or white balance settings of the camera.
The aim of this paper is to integrate existing methods of histogram transfers used in the domain of computational photography into mixed-reality environments. These methods allow us to simulate current luminance conditions in the scene and changes in the camera driver settings to apply them onto virtual objects.
This thesis contains two fast-running approaches to provide a color mapping between virtual objects and the real scene, which can be used in real-time applications. The results show that these methods increase the immersion of virtual objects in a real scene.
