| Abstract(in English) | It is necessary to reduce two variance values of the degradation level of stego images and the embedding rate in steganography techniques. We proposed a technique in revaluating threshold levels for judging complexity boundary. This technique can be achieved by determining the complexity distributions, which is consisted by the complexity gained by the judgment of complexity, and the number of macroblocks having the complexity in the BPCS steganography technique, and confirmed the effectiveness. However, parameters used in reevaluation of threshold levels aren't in correlation with the complexity distributions and are set arbitrarily. In this paper, we proposed technique parameters set automatically by a standard deviation of a normal distribution and confirmed the effectiveness by the experiments. |
