基于图像显著区域的自动标注方法的准确率与整体考虑整幅图像特征相比有很大提高，表明提出的算法优于传统方法。-a novel algorithm based on image saliency is demonstrates the proposed approach is promising．

LSB（Least  Significant  Bit）算法是将秘密信息嵌入到载体图像像素值的最低有效位，也称最不显著位，改变这一位置对载体图像的品质影响最小。-LSB (further Significant Bit) algorithm is to embed the secret information carrier image pixel values of the Least Significant Bit, also known as the Least Signi
