ABSTRACT

The integration of virtual renderings into video images is of great importance for many applications of computer graphics such as TV and movie production and augmented reality. This submission proposes and examines methods for a smooth transition from real to virtual image regions along the boundaries of graphical objects. This constitutes a new form of antialiasing, which --- unlike its counterpart in purely virtual images --- has not been systematically investigated so far. We introduce real-virtual supersampling based on the combination of a high-resolution rendering of the graphical elements and an upsampled version of the video image. Several different methods for image upsampling are discussed. We compare results obtained through these methods with simple image combination methods: image overlay without antialiasing and pixel averaging in the original image resolution.
