	abstract = {We introduce an epitomic representation for modeling human activities in video sequences. A video sequence is divided into segments within which the dynamics of objects is assumed to be linear and modeled using linear dynamical systems. The tuple consisting of the estimated system matrix, statistics of the input signal and the initial state value is said to form an epitome. The system matrices are decomposed using the Iwasawa matrix decomposition to isolate the effect of rotation, scaling and projective action on the state vector. "We demonstrate the usefulness of the proposed representation and decomposition for activity recognition using the TSA airport surveillance dataset and the UCF indoor human action dataset.},

	abstract = {In this paper, we consider aggregating multiple video streams and transmitting the merged stream over multiple error-prone paths. We propose a novel multi-stream error protection scheme based on packet division multiplexing access (PDMA) and cross-path forward error coding. Compared with the traditional time division multiplexing access (TDMA)-based error protection scheme, the proposed scheme outperforms 1.43 1.88 dB for the averaged PSNR of all received streams},

	abstract = {The paper proposes novel data hiding algorithms and system design for high quality digital video. Instead of targeting on a single degree of robustness, which results in overestimation and/or underestimation of the noise conditions, we apply multi-level embedding to digital video to achieve more than one level of robustness-capacity tradeoff. In addition, an adaptive technique is proposed to determine how many bits are embedded in each part of the video. Besides user data, control information such as synchronization and the number of hidden user bits are embedded as well. The algorithm can be used for applications such as access control},
