Can virtual look real? A review of virtual studio techniques

摘要

The goal of all the techniques presented above is to combine two separate images-camera foreground and computer-generated background-so well that the composite looks as if it was shot together, in one environment. This is not an easy task, since human visual system is very picky in detecting all incorrect subtleties, even though the nature of an error need not be consciously recognized. In the light of the discussions presented in this paper, we can say that reaching such a level of realism Is very difficult, and even impossible in a general case.
