Infrared-camera-based metamer marker for use in dark environments

초록

We propose an invisible metamer marker that can be used in low illumination environments. The proposed marker is not visible to the eye as the color of the background is similar. In our system, the marker and the background image look differently in the infrared camera image by using different printers for each region. The proposed method is able to produce uniform quality unlike existing invisible markers. Based on these metamerism features in infrared band, markers can be successfully used even in low light and dark environments and the commercial applicability is high.
