A method of spatial overlap-add is utilized in this algorithm. It can reduce the block noise exist in the traditional DCT watermarking algorithm and improve the quality of the image.

通过空间交迭的方法，该算法能够削弱传统DCT自适应水印算法的块状噪声，从而提高图像的品质。

Although you can add a time component to the tagging entity, doing so is discouraged because differing time zones can cause overlap and conflicts.

虽然可以在标签实体中增加时间成分，但不鼓励这么做，因为不同时区可能造成重叠和冲突。
