360-Degree VR Video Watermarking Based on Spherical Wavelet Transform
(2021)Similar to conventional video, the increasingly popular 360 virtual reality (VR) video requires copyright protection mechanisms. The classic approach for copyright protection is the introduction of a digital watermark into ... -
AVS video decoder on multicore systems: Optimizations and tradeoffs
(2011)Newer video compression standards provide high video quality and greater compression efficiency, compared to their predecessors. Their increased complexity can be outbalanced by leveraging all the levels of available ... -
Bone fracture identification in x-ray images using fuzzy wavelet features
(2019)The fracture detection process is difficult and requires specialized knowledge of the anatomical structures of the area under consideration. X-ray imaging provides images of the body's internal structures. Despite the rapid ... -
Cross-layer optimized authentication and error control for wireless 3D medical video streaming over LTE
(2017)3D video for tele-medicine applications is gradually gaining momentum since the 3D technology can provide precise location information. However, the weak link for 3D video streaming is the necessary wireless link of the ... -
Efficient Cloud Provisioning for Video Transcoding: Review, Open Challenges and Future Opportunities
(2018)Video transcoding is the process of encoding an initial video sequence into multiple sequences of different bitrates, resolutions, and video standards, so that it can be viewed on devices of various capabilities and with ... -
Efficient high-performance ASIC implementation of JPEG-LS encoder
(2007)This paper introduces an innovative design which implements a high-performance JPEG-LS encoder. The encoding process follows the principles of the JPEG-LS lossless mode. The proposed implementation consists of an efficient ... -
Evaluation of heterogeneous scheduling algorithms for wavefront and tile parallelism in video coding
(2019)Video is by far the “biggest” Big Data, stretching network and storage capacity to their limits. To handle the situation, video compression has been an active field of study for many years, producing output of huge commercial ... -
A framework for scheduling the encoding of multiple smart user videos
(2016)The ever increasing number of video uploads in social media platforms, together with the incorporation of live video broadcasts and a growing demand for higher video resolution, will likely pose the most significant ... -
HEVC decoder optimization in low power configurable architecture for wireless devices
(2015)High Efficiency Video Coding (HEVC) is the new video compression standard, reducing bitrates nearly at half compared to H.264, offering potentially significant power savings for wireless video transmission at the network ... -
Implementation and performance comparison of the motion compensation kernel of the AVS video decoder on FPGA, GPU and multicore processors
(2011)Next generation video standards have strict and increasing performance demands due to real-time requirements and the trend towards higher frame resolutions and bit rates. Leveraging the advantages of reconfigurable logic ... -
Mapping and optimization of the AVS video decoder on a high performance chip multiprocessor
(2010)Modern multimedia workloads provide increased levels of quality and compression efficiency at the expense of substantially increased computational complexity. It is important to leverage the off-the-shelf emerging multi-core ... -
On the Evaluation of Coarse Grained Parallelism in AV1 Video Coding
(2018)Video compression is arguably one of the most time consuming tasks, especially at high resolutions. For this reason parallelization has been used at various levels: from coarse grained schemes that consider groups of blocks ... -
Wavelet-based compression with ROI coding support for mobile access to DICOM images over heterogeneous radio networks
(2009)Most of the commercial medical image viewers do not provide scalability in image compression and/or region of interest (ROI) encoding/decoding. Furthermore, these viewers do not take into consideration the special requirements ...
