Photometric inconsistency on a mixed-reality face

A mixed-reality face (MR face) is a mosaic face with real and virtual facial parts. It is presented by overlaying a virtual facial part onto a real face by using mixed-reality techniques. An MR face is effective to improve the communication in the mixed-reality space by restoring the eye expression which is lost by wearing HMDs. The photometric registration between the real and the virtual parts is important because our eyes are very sensitive even to small changes on human faces. However, the efforts to achieve the perfect ’physical’ photometric registration on an MR face are not feasible in an ordinary MR space. It is essential to clarify the sensitivity of our eyes to the photometric inconsistencies on an MR face, and to concentrate the efforts for resolving the inconsistencies which are sensitive to our eyes. In this paper, we first present the results of a systematic experiment to evaluate our sensitivity to the photometric inconsistency on an MR face. Then, the technique to...
