Simultaneous 2D and 3D perception for stereoscopic displays based on polarized or active shutter glasses

•The goal is to enable simultaneous 3D/2D perception with/without viewing glasses.•One view in stereoscopic video is manipulated to make it similar to the other view.•The proposed steps are: disparity selection, contrast adjustment, lowpass filtering.•Extensive subjective tests were conducted to evaluate the proposed algorithm.•Results show that the proposed method provides acceptable 2D and 3D quality.

Viewing stereoscopic 3D content is typically enabled either by using polarizing or active shutter glasses. In certain cases, some viewers may not wear viewing glasses and hence, it would be desirable to tune the stereoscopic 3D content so that it could be simultaneously watched with and without viewing glasses. In this paper we propose a video post-processing technique which enables good quality 3D and 2D perception of the same content. This is done through manipulation of one view by making it more similar to the other view to reduce the ghosting artifact perceived without viewing glasses while 3D perception is maintained. The proposed technique includes three steps: disparity selection, contrast adjustment, and low-pass filtering. The proposed approach was evaluated through an extensive series of subjective tests, which also revealed good adjustment parameters to suit viewing with and without viewing glasses with an acceptable 3D and 2D quality, respectively.
