发明名称 Video watermarking using temporal analysis
摘要 Methods of embedding and detecting watermarks in video use temporal analysis to compute temporal components of video from which the watermarks are embedded and detected. Temporal analysis, such as a temporal wavelet, is used to compute representations of static and dynamic portions of the video. For embedding, watermarks are computed from and/or adapted to the temporal components. For detecting, temporal properties are exploited to detect watermarks in the static and/or dynamic components. Temporal analysis also enables plural watermarks to be embedded at different levels of temporal resolution.
