| description | Dual-view display is a technology that provides two different views concurrently for different users on a single medium. We propose a dual-view display system, where users can see one view through a pair of specific glasses (called personal view) and see another view without the glasses (called shared view). The display technology can be of great use in practice. For instance, in the application of information security display, the user with the specific glasses can see the private information but bystanders can only see an unrelated/disguising view. The dual-view display is based on an information display technology called spatial psychovisual modulation (SPVM). The rationale behind SPVM is that modern displays have high resolutions and can provide information beyond what human visual system can resolve, i.e., modern displays have spatial psychovisual redundancy. The redundancy of high-resolution displays can be exploited to achieve dualview or even multi-view display. In this paper, we introduce heuristic and iterative algorithms for the dualview display. The iterative algorithm utilizes the Gaussian-like spatial integration window of human eyes. Compared with the heuristic algorithm, the iterative algorithm has significant improvements for the shared view with preference in percentage of 90.2% on average. This paper serves as a guidance for dual-viewbased applications. Moreover, the method discussed in this paper can be also used to explore the temporal redundancy of displays. |
