Design and implementation of a teleconferencing system using improved HEVC codingJournal of Real-Time Image Processing - Tập 12 - Trang 383-395 - 2016
Shaima’ Safaaldin, Ergun Erçelebi
Teleconferencing has become an indispensable element
in any business system, because it offers the opportunity for collaborators to participate in a virtual group while remaining in divergent regions. Teleconferencing also increases productivity, minimizes travel expenses and saves travel time. This paper presents a reliable Teleconference system that utilizes an improved high-efficiency video co...... hiện toàn bộ
Deep learning-based real-time VPN encrypted traffic identification methodsJournal of Real-Time Image Processing - Tập 17 - Trang 103-114 - 2019
Lulu Guo, Qianqiong Wu, Shengli Liu, Ming Duan, Huijie Li, Jianwen Sun
With the widespread application of virtual private network (VPN) technology, real-time VPN traffic identification has become an increasingly important task in network management and security maintenance. Since traditional encrypted traffic identification technology is not effective in feature extraction and selection, this paper proposes two deep learning-based models to classify the traffic into ...... hiện toàn bộ
A real-time SC2S-based open-set recognition in remote sensing imageryJournal of Real-Time Image Processing - Tập 19 - Trang 867-880 - 2022
Dubacharla Gyaneshwar, Rama Rao Nidamanuri
Accuracy and computational time are two crucial parameters influencing the efficacy of classification algorithms for remote sensing applications. Machine learning algorithms are known for achieving notable success for several classification problems in various domains, including remote sensing. However, they are well-recognized and considered accurate and efficient for closed-set recognition (CSR)...... hiện toàn bộ
Embedded GPU implementation of sensor correction for on-board real-time stream computing of high-resolution optical satellite imageryJournal of Real-Time Image Processing - Tập 15 - Trang 565-581 - 2017
Mi Wang, Zhiqi Zhang, Ying Zhu, Zhipeng Dong, Yingying Li
In recent years, the data generation rate of high-resolution optical satellites is increasing rapidly, and this situation brings massive stress to the data downloading link and data processing system. To relieve downloading link stress and enhance the time efficiency of information acquisition, on-board processing needs to be introduced. Current on-board solutions are mostly based on digital signa...... hiện toàn bộ
Visual secret sharing scheme for (k, n) threshold based on QR code with multiple decryptionsJournal of Real-Time Image Processing - Tập 14 - Trang 25-40 - 2017
Song Wan, Yuliang Lu, Xuehu Yan, Yongjie Wang, Chao Chang
In this paper, a novel visual secret sharing (VSS) scheme based on QR code (VSSQR) with (k, n) threshold is investigated. Our VSSQR exploits the error correction mechanism in the QR code structure, to generate the bits corresponding to shares (shadow images) by VSS from a secret bit in the processing of encoding QR. Each output share is a valid QR code that can be scanned and decoded utilizing a Q...... hiện toàn bộ
Fast computation of 2D and 3D Legendre moments using multi-core CPUs and GPU parallel architecturesJournal of Real-Time Image Processing - Tập 16 - Trang 2027-2041 - 2017
Khalid M. Hosny, Ahmad Salah, Hassan I. Saleh, Mahmoud Sayed
Legendre moments and their invariants for 2D and 3D image/objects are widely used in image processing, computer vision, and pattern recognition applications. Reconstruction of digital images by nature required higher-order moments to get high-quality reconstructed images. Different applications such as classification of bacterial contamination images utilize high-order moments for feature extracti...... hiện toàn bộ
A hardware/software prototyping system for driving assistance investigationsJournal of Real-Time Image Processing - Tập 11 - Trang 559-569 - 2013
Jakob Anders, Michael Mefenza, Christophe Bobda, Franck Yonga, Zeyad Aklah, Kevin Gunn
A holistic design and verification environment to investigate driving assistance systems is presented, with an emphasis on system-on-chip architectures for video applications. Starting with an executable specification of a driving assistance application, subsequent transformations are performed across different levels of abstraction until the final implementation is achieved. The hardware/software...... hiện toàn bộ
Architecture for parallel marker-free variable length streams decodingJournal of Real-Time Image Processing - Tập 16 - Trang 2127-2146 - 2017
Yousef Baroud, José Manuel Mariños Velarde, Zhe Wang, Steffen Kieß, Seyyed Mahdi Najmabadi, Jajnabalkya Guhathakurta, Sven Simon
Due to throughput requirements above 1 gigapixel/sec for the real-time compression of modern image and video data streams, parallelism for encoding and decoding is inevitable. To achieve parallel decoding, a well-established technique is to insert markers into the variable length code (VLC) stream. By locating markers, it is then possible to extract the sub-streams that are, in turn, decoded in pa...... hiện toàn bộ
Smart and real-time image dehazing on mobile devicesJournal of Real-Time Image Processing - Tập 18 - Trang 2063-2072 - 2021
Yucel Cimtay
Haze is one of the common factors that degrades the visual quality of the images and videos. This diminishes contrast and reduces visual efficiency. The ALS (Atmospheric light scattering) model which has two unknowns to be estimated from the scene: atmospheric light and transmission map, is commonly used for dehazing. The process of modelling the atmospheric light scattering is complex and estimat...... hiện toàn bộ
