| Research Abstract |
We studied the technique that could embed the information in the image of the object taken by the camera using the brightness-modulated illumination that contained invisible binary information. We conducted experiments to evaluate the feasibility of the technology and demonstrated that one-bit binary data could be embedded invisibility in each of many small 2-D blocks or 1-D lines and embedded data could be read out accurately. We also demonstrated that we could embed the depth map in the images captured with a camera using illumination for the object that contained invisible pattern whose characteristics depended on depth of the object
