Design of Imperceptible Metamer Markers and Application Systems
2020
IEEE Access
Preserved Fulltext
This paper presents a application system using imperceptible metamer markers. The proposed system is based on metamer markers that are invisible to the human eye but visible to infrared (IR) cameras. ...
The metamer markers are expected to be very useful for AR applications, projector-camera systems, human-computer interaction systems, and so on. ...
A fairytale book (asia zodiac signs story) that can be used in various camera-projector based e-learning systems was created to show the application effects of the metamer marker proposed in this paper ...

For naturally semitransparent structures, such as roots, live 3D imaging using OPT is also possible. 3D domains of gene expression can be visualized using either marker genes, such as b-glucuronidase, ...
To address this, we have explored the use of optical projection tomography (OPT) as a method for capturing 3D data from plant specimens. ...
Visible light transmission images were collected using a 20-W halogen lamp connected to the OPT device. Infrared path filters (700, 750, and 800 nm) reduced dark signal in strongly stained specimens. ...
