Research ArticleOpen accessEvery word in the titleA Survey on Joint Compression and Encryption Techniques for Video DataK. John Singh, R. ManimegalaiProblem statement: When we send any video data over the network it consumes more time. This is due to the huge size of the video file when compared to text file. Therefore, video data should be compressed before sending to the destination. Another important factor during data transfer is security. Joint compression and encryption is employed to enable faster and … …Journal of Computer Science, Vol. 8, Issue 5 · 28 Feb 2012 · 7,344 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFuzzy Logic Controller for Wireless Video TransmissionK. P. Rajesh, K. S. RamaswamiProblem statement: As the Variable Bit Rate (VBR) is high in MPEG, the video experienced long delay and unexpected data loss. In wireless channel, due to noise and interference of other signals transmission rate cannot be predicted. Approach: In this paper we proposed an intelligent fuzzy logic controller for transmission of Moving Picture Expert Group (MPEG-4) video signals over wireless … …Journal of Computer Science, Vol. 7, Issue 7 · 30 Jun 2011 · 6,950 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleA Robust Video Watermarking AlgorithmTahani Al-Khatib, Ali Al-Haj, Lama Rajab, Hiba MohammedProblem statement: Video watermarking is well known as the process of embedding copyright information in video bit streams. It had been proposed in recent years to solve the problem of illegal manipulation and distribution of digital video. Approach: In this study, an effective, robust and imperceptible video watermarking algorithm was proposed. This algorithm was based on a cascade of two … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,870 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Depth Estimation System for Laboratory Studies using Video ImageryAlec Torres, Rodolfo SilvaA simple video-based system has been developed for depth estimation based on wave propagation characteristics. A numerical simulation of a long-crested monochromatic wave propagating over a beach with straight and parallel contours is used for testing the depth inversion system. An oblique video, simulating field conditions, is recorded, digitized and rectified for its further analysis. Pixel intensity time series from … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 6,655 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSimplified Block Matching Algorithm for Fast Motion Estimation in Video CompressionM. Ezhilarasan, P. ThambiduraiBlock matching motion estimation was one of the most important modules in the design of any video encoder. It consumed more than 85% of video encoding time due to searching of a candidate block in the search window of the reference frame. To minimize the search time on block matching, a simplified and efficient Block Matching Algorithm for Fast Motion … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 7,041 accessesView PDFCite
