| Abstract(in English) | This paper proposes an improvement for a data embedding method to printed images based on spread spectrum. This technique is based on DCT and PN sequences. First, the conventional embedding method is introduced. In the conventional method, deformations, such as rotation and scaling, have given a serious defect to the extraction rate. To solve this problem, a new data embedding position and the processing by the resolution of scanner itself are applied. An adaptive control technique of the gain coefficient is also proposed. Finally, the simulation result shows the improvement of the extraction rate by the proposed method and the effectiveness of the proposed method. |
