亦即其中一個藏入演算法採用正向增加或位移，另一演算法則採用負向減少或位移，使得重疊區塊的像素，在兩次重疊藏入的過程中，藏入前後的像素差距不超過1，並有約一半的機會，在藏入後仍保持原值。

結果 (英文) 1:

I.e., wherein the algorithm uses a hidden or forward displacement increases, another algorithm is used to reduce or negative displacement, so that the overlapping pixel blocks, in the course of the two overlapping reservoirs into the possession of a pixel before and after the gap is not more than one opportunity, and about half of the original value after hiding the remains.

結果 (英文) 2:

That is, one of the hiding algorithms uses positive increase or displacement, and the other algorithm uses negative reduction or displacement, so that the pixels of overlapping blocks, in the process of two overlapping hiding, the pixel gap before and after hiding does not exceed 1, and there is about half the chance to remain the original value after hiding.

結果 (英文) 3:

That is to say, one algorithm uses positive increase or displacement, the other algorithm uses negative decrease or displacement, so that in the process of two overlapped hiding, the difference between the pixels before and after hiding does not exceed 1, and there is about half chance to keep the original value after hiding.
