文章研究了将一张彩色的隐藏图像嵌AN另一张彩色载体网像的图像隐藏算法。通过对隐藏图像的DCT变换，对提取出的低频系数进行二进制编码，并与中频系数共同构成用于隐藏的特征信息；对载体图像进行DCT变换来确定信息隐藏的位置。通过抗攻击性测试表明本隐藏算法具有很强的稳健性。

In order to ensure the security of the image＇s transmitting, a hiding scheme for holding an image into another was discussed in this paper. By making DCT transformation for hidden image, the coefficients of low frequency made into binary coded information, was used as feature information with the middle frequency coefficients together. Making DCT transformation for carrier image can determine the location where embed the feature information. The test of attack indicated that the scheme is effective and steady.
