PRE-PROCESSED INFORMATION EMBEDDING SYSTEM

摘要

Methods and devices are provided for reducing perceptible artifacts in a host content when the host contend is embedded with watermarks. In one method, a first segment of a host content that includes a first logical value is obtained. A second segment of the host content that includes a second logical embedded therein is also obtained. The second logical value is different from the first logical value, and the second segment is adjacent to the first segment of the host content. The host content at a boundary location of the first and the second segments is modified according to a transition function to suppress transitions in the host content at the boundary location caused by the different logical values embedded in the first and the second segments of the host content.
