A 2DPCA-Based Video Watermarking Scheme for Resistance to Temporal Desynchronization
نویسندگان
چکیده
Temporal synchronization is a problem that cannot be ignored in most video watermarking application. In this paper, a video watermarking scheme is proposed to resist temporal desynchronization by using shot segmentation and two-dimensional principal component analysis (2DPCA). In this scheme, the to-be-watermarked video is first segmented into different shots. And each shot is analyzed by 2DPCA in xt tomography to get its principal feature frames (PFFs). And then the watermark is embedded into the PFFs. This scheme is robust to temporal desynchronization through a content dependent way. Simulations show the feasibility and reliability of this scheme. It is also robust to most of the common video processing/attacks, such as MPEG2 compression, filtering, frame resizing, noising, etc.

A Robust Video Watermarking Scheme Via Temporal Segmentation and Middle Frequency Component Adaptive Modification
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...
متن کاملRobust multiplicative video watermarking using statistical modeling
The present paper is intended to present a robust multiplicative video watermarking scheme. In this regard, the video signal is segmented into 3-D blocks like cubes, and then, the 3-D wavelet transform is applied to each block. The low frequency components of the wavelet coefficients are then used for data embedding to make the process robust against both malicious and unintentional attacks. Th...
متن کاملTwo Novel Chaos-Based Algorithms for Image and Video Watermarking
In this paper we introduce two innovative image and video watermarking algorithms. The paper’s main emphasis is on the use of chaotic maps to boost the algorithms’ security and resistance against attacks. By encrypting the watermark information in a one dimensional chaotic map, we make the extraction of watermark for potential attackers very hard. In another approach, we select embedding po...

One of the most important practical problems of blind Digital Watermarking is the resistance against desynchronization attacks, one of which is the Stirmark random bending attack in the case of image watermarking. Recently, new blind digital watermarking schemes have been proposed which do not suffer from host-signal interference. One of these quantization based watermarking scheme is the Scala...
