Recently, several data extraction methods from data embedding printing images by using cellular phones with a camera have been proposed. In this technique, consideration for geometrical deformation and lens distortion in the data extraction process is essential. This paper proposes new correction algorithm based on line based correction (LBR) and perspective transformation to the scanning of the printing images for reduction of the geometrical deformation by the camera. This method can be applied to both of barrel and pin cushion distortion. To increase the amount of embedding data, a new data embedding method in which the codes for data embedding are changed according to the embedding data is also proposed and a gain control technique suitable for this method is developed. From experiment results, effectiveness of the proposed method for the color image is shown. |
