Using infrared watermark technology to design AR markers with different hiding effects
Chun‐Hsien Wang, Hsi-Chun Wang · 2014
This paper presents a method using infrared watermark technology to design augmented reality (AR) marker with different hiding effects. By adopting both amplitude modulation (AM) and frequency modulation (FM) halftone dots, infrared watermark with AR marker pattern can be composed by varied optical properties of YMCK inks under infrared detection. The visibility of AR marker can be fine-tuned according to the density calibration chart.
