Abstract

A robust video watermarking scheme via temporal segmentation and middle frequency component adaptive modification is presented. First, the video clip is sliced into a shot sequence by temporal video segmentation. Then, several consecutive shots are selected from the shot sequence to makeup a video segment with proper duration. The watermark is embedded into the video segment by equally dividing it into many units, and modifying the middle frequency component of frames in each unit. In addition, the scheme adjusts the modification strength of every coefficient adaptively according to the change between consecutive frames and Watson’s DCT based visual model. Experimental results show that the scheme is resilient to many kinds of temporal desynchronization, spatial desynchronization and photometric distortion at the same time.
