Description: We propose a novel approach for head tracking, which combines particle filters with Isomap. The particle filter works on the low-dimensional embedding of training images. It indexes into the Isomap with its state variables to find the closest template for each particle. The most weighted particle approximates the location of head. We develop a synthetic video sequence to test our technique. The results we get show that the tracker tracks the head which changes position, poses and lighting conditions.

Firstly, a video stream is divided into scenes, scenes of the video image is converted to the DCT-SVD domain, the watermark embedded in the largest singular quantification, the realization of the watermark signal. Furthermore, the experiments show that the algorithm meet the transparency requirements are met under certain robustness requirements, can resist the low-pass filtering, median filtering, salt and pepper noise, Gaussian noise, H.264 compression attacks and attacks and frame shear statistics attack.

Description: Abstract—Based on the observation that low-frequency DCT
coefficients of an image are less affected by geometric processing,
we propose a new blind MPEG-2 video watermarking algorithm
robust to camcorder recording. Both the embedding and
extraction of the watermarks are done in the compressed domain.
The mean of the low-frequency DCT coefficients of the video is
temporally modulated according to the information bits. To
reduce complexity, we embed watermark in the prediction error
signals of the B-frames. Experimental results show that the
proposed scheme achieves high video quality and robustness to
camcorder recording, trans-coding, frame-rate conversion, and
geometric attacks on common test videos.

Description: Recently, digital multimedia has become widely distributed in computer and network technology. For digital
multimedia distribution applications, issues surrounding information security have received significant attention. Data hiding has been one of most researched issues in information security. In this paper, reversible video data hiding based on neighborhood similarity is proposed. Prediction encoding was used to compute the prediction errors. All prediction errors were explored to develop a histogram-based reversible video data hiding algorithm. The results show that the proposed
approach has a higher capacity and similar embedding distortion compared with other related schemes. Also, the original
video frame could be recovered after the hidden information was extracted.
