Confidentiality and Privacy for Videos Storage and Transmission

by Shaimaa A. El-said, Khalid F. A. Hussein, Mohamed M. Fouad
"... Security and privacy issues of the transmitted data have become an important concern in multimedia technology. In this paper, we propose a computationally efficient and secure video encryption algorithm. This makes secure video encryption feasible for real-time applications without any extra dedicat ..."

takes only 2 ms of encryption time per frame. This paper deals with the issues of color videos in-compression encryption, this done by using the optimized multiple Huffman table (OMHT) technique, will be elucidated upon in order to compress and encrypt both color images and videos. Only visual

Support for Fully Interactive Playout in a Disk-Array-Based Video Server

by Ming-syan Chen, Dilip D. Kandlur, Dilip D. K, Philip S. Yu - In Proceedings of the Second International Conference on Multimedia , 1994
"... In a video--on--demand (VOD) system, it is desirable to provide the user with interactive browsing functions such as "fast forward" and "fast backward." However, these functions usually require a significant amount of additional resources from the VOD system in terms of storage s ..."

Perception-motivated High Dynamic Range Video Encoding

by Rafal Mantiuk , Grzegorz Krawczyk, Karol Myszkowski, Hans-Peter Seidel - ACM TRANSACTIONS ON GRAPHICS , 2004
"... Due to rapid technological progress in high dynamic range (HDR) video capture and display, the efficient storage and transmission of such data is crucial for the completeness of any HDR imaging pipeline. We propose a new approach for inter-frame encoding of HDR video, which is embedded in the well-e ..."

-established MPEG4 video compression standard. The key component of our technique is luminance quantization that is optimized for the contrast threshold perception in the human visual system. The quantization scheme requires only 10--11 bits to encode 12 orders of magnitude of visible luminance range and does

CVEPS- A Compressed Video Editing and Parsing System

by unknown authors
"... Processing digital video directly in the compressed domain has many advantages in terms of storage efficiency, speed, and video quality. We have developed a compressed video editing and parsing system (CVEPS) with advanced video indexing and manipulation functions. The video parsing tools support au ..."

Compressed Domain Processing of JPEG-encoded images

by Brian C. Smith, Lawrence A. Rowe - Real-Time Imaging , 1996
"... This paper addresses the problem of processing motion-JPEG video data in the compressed domain. The operations covered are those where a pixel in the output image is an arbitrary linear combination of pixels in the input image, which includes convolution, scaling, rotation, translation, morphing, de ..."

-time rates on current generation workstations. 1 Introduction Processing video data is problematic due to the high data rates involved. Television quality video requires approximately 100 GBytes for each hour, or about 27 MBytes for each second. Such data sizes and rates severely stress storage systems

Efficient Compression Of Arbitrary Multi-View Video Signals

by Jeffrey Scott McVeigh , 1996
"... Multiple views of a scene, obtained from cameras positioned at distinct viewpoints, can provide a viewer with the benefits of added realism, selective viewing, and improved scene understanding. The importance of these signals is evidenced by the recently proposed Multi-View Profile (MVP) extension t ..."

to the MPEG-2 video compression standard, and their explicit incorporation into the future MPEG-4 standard. However, multi-view compression implementations typically rely on single-view image sequence model assumptions. We hypothesize (and demonstrate) that impressive system bandwidth reduction can

Authoring, Compression, and Playback of Active Video Content

by Anindya Neogi, Advisor Prof, Tzi-cker Chiueh
"... Conventional digital video playback systems provide only limited user interactivity, mostly in the form of VCRlike controls such as fast forward/backward, slow motion, pause/stop, etc. In this model, the temporal ordering and the spatial viewpoints of the video streams being viewed are completely ..."

in video sequences. The tool incorporates novel lossy and lossless compression algorithms to reduce additional storage costs and disk bandwidth overhead associated with active video content. We propose to build an active video server (AVS) to store and deliver the active video content created using

Real-Time Video Content Analysis Tool for Consumer Media Storage System

by Jungong Han, Dirk Farin, Peter H. N. De, Senior Member, Weilun Lao , 2006
"... Abstract — With the growing storage capacities of harddisks and optical discs, large consumer video databases are gradually developing. The large effective storage capacity using compressed video leads to the application of fast storage and retrieval functions, to enable quick user-friendly searchin ..."
