Psycho-visual modulation based information display: introduction and survey

摘要

Industry and academia have been making great efforts in improving refresh rates and resolutions of display devices to meet the ever increasing needs of consumers for better visual quality. As a result, many modern displays have spatial and temporal resolutions far beyond the discern capability of human visual systems. Thus, leading to the possibility of using those display-eye redundancies for innovative usages. Temporal/spatial psycho-visual modulation (TPVM/SPVM) was proposed to exploit those redundancies to generate multiple visual percepts for different viewers or to transmit non-visual data to computing devices without affecting normal viewing. This paper reviews the STPVM technology from both conceptual and algorithmic perspectives, with exemplary applications in multi-view display, display with visible light communication, etc. Some possible future research directions are also identified.
