| 摘 要： | 提出了基于误差扩散的二值化编码算法，此算法在进行二值化误差扩散的同时加入给定的编码，即用变化的阈值代替固定的阈值，使单纯的二值化算法具有嵌入编码的能力，并能有效地、可靠地嵌入和提取编码．经过对样图进行具体的算法实施，其嵌入编码都能被正确无误地提取出来．结果表明该算法是可行、有效的，具有很好的实用性．

| Abstract: | A two-state coding algorithm based on the error diffusion was proposed,which made the two-state algorithm have the function of hiding the coding with variational threshold substituting for aptotic threshold,could embed and pick up the coding effectively and accurately.After implementing the concrete algorithm to the master drawing,its hide codes can be all drawing out with none mistake.The results showed that this algorithm was feasible,effective,and practicable. |
