Data extraction from data-embedded printed image using embedding markers for image correction

In this paper, we propose a new method of embedding data and extracting it from a printed image. By embedding the data in a translation-invariant region of a target image, extraction of the target image from the background becomes unnecessary. Therefore, the data can be embedded at an arbitrary position in the target image. Additionally, a marker detection method using invisible markers is proposed to correct the geometrical distortion in the captured image. From our experimental results, the effectiveness of the proposed method is shown.
