Abstract (in Japanese) (See Japanese page) 
(in English) It is necessary to reduce two variance values of a degradation level of stego images and an embedding rate in steganography techniques. We proposed a technique reevaluating threshold levels for judging complexity boundary by the complexity distributions consisting of complexity gained by judgment of complexity and the number of macroblocks having the complexity in BPCS steganography technique. There are various complexity judging methods based on side lengths of the boundary line, DF-expressions, 4-neighbor, 8-neighbor, etc. In this paper, we discussed the most suitable judging method using the variance values and the computation time calculated by various complexity judging methods on the complexity judgment in proposed technique.
