| Outline of Final Research Achievements |
We studied on technique that can embed information in a captured image of an object by using structured light by invisible pattern. It was clarified that the information can be read out with high accuracy by structuring light with color difference signals and embedding information is resistant to JPEG compression. We proposed a method of erasing the information written by light and embedding the information again by digital processing, as a method of simultaneously satisfying the high density and invisibility of the embedded information, which are in a trade-off relationship, and demonstrated the effect. Moreover, it was clarified that the use of GAN is effective for erasing information. This method enables embedding of three-dimensional information in a two-dimensional image and expands the range of application of this technology.
