Data extraction methods from data embedding printing images by capturing devices like scanners have attracted much attention. In this technique, consideration for geometrical deformation, especially rotations, in the data extraction process is essential. For this correction, addition of a black frame to the image as the marker has been considered. However it may not be preferable in some case, since the fame may change the impression of images. This paper proposes new correction algorithm without remarkable markers based on the watermarking technique. This method can adopt the relationship between the mark in DFT domain and the rotation of images. By embedding the mark in DFT domain, the rotational angle can be easily obtained. Related to this new embedding marker, the area in DCT domain for embedding the information is investigated. Also an image resize technique suitable for this method is developed. From experiment results, effectiveness of the proposed method is shown. |
