Research ArticleOpen accessPhrase in the titleAn Efficient Video Compression Framework using Deep Convolutional Neural Networks (DCNN)Kommerla Siva Kumar, P. Bindhu Madhavi, K. JanakiIn the current world, video streaming has grown in popularity and now accounts for a large percentage of internet traffic, making it challenging for service providers to broadcast videos at high rates while utilizing less storage space. To follow inefficient analytical coding design, previous video compression prototypes require non-learning-based designs. As a result, we propose a DCNN technique that integrates … …Journal of Computer Science, Vol. 18, Issue 7 · 13 Jul 2022 · 6,153 accessesView PDFCite
Research ArticleOpen accessPhrase 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
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

The main objective of this tutorial paper is to highlight state of the art on video streaming and the most … …Journal of Computer Science, Vol. 14, Issue 4 · 21 Apr 2018 · 7,953 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPerformance, Analysis of Filtering Schedule Using Deblocking Filter for the Reduction of Block Artifacts from MPEQ Compressed Document ImagesM. Anto Bennet, I. Jacob RaglendProblem statement: The visual effects of blocking artifacts can be reduce by using deblocking filter. Also with out smoothing the natural edges,the perceived quality of video sequence can be enchanced. This study propose a method to remove blocking artifacts in low bit-rate block based video coding. Approach: The proposed algorithm has two separate filtering modes, which are selected by pixel … …Journal of Computer Science, Vol. 8, Issue 9 · 8 Aug 2012 · 7,264 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSingle Core Hardware Module to Implement Partial Encryption of Compressed ImageMamun Bin Ibne Reaz, Md. Syedul Amin, Fazida Hanim Hashim, Khandaker AsaduzzamanProblem statement: Real-time secure image and video communication is challenging due to the processing time and computational requirement for encryption and decryption. In order to cope with these concerns, innovative image compression and encryption techniques are required. Approach: In this research, we have introduced partial encryption technique on compressed images and implemented the algorithm on Altera FLEX10K FPGA device that … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 7,379 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDigital Video Watermarking in the Discrete Cosine Transform DomainSadik Ali M. Al-Taweel, Putra Sumari, Saleh Ali K. Alomari, Anas J.A. HusainProblem statement: Nowadays, digital watermarks have recently become recognized as a solution for protecting copyright of the digital multimedia. For a watermark to be useful, it must be perceptually invisible and robust against any possible attack and image processing by those who seek to corsair the material, researchers have considered various approaches like JPEG compression, geometric distortions and noising. Approach: … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 7,246 accessesView PDFCite
Research ArticleOpen accessIn the abstractAbstractive Summarization of Long Educational Transcripts in the Era of GenAIDeepa Fernandes, Rupali Sunil WaghThe surge in online video data presents the imperative requirement of summarizing it for information compression, efficient understanding, and to support decision-making. Recent research studies have predominantly utilized structured input data for summarization. This paper explores the current state-of-the-art models in summarizing unstructured, conversational, and long transcript data. We further apply a transfer learning approach using a fine-tuned BART model, … …Journal of Computer Science, Vol. 22, Issue 8 · 7 Sep 2026 · 403 accessesView PDFCite
