On the optimal processor assignment for computing the steady state kalman filter in parallel and distributed systems
(2017)Kalman filters have many practical applications in various fields such as sensor networks, image and video processing. Therefore, their fast computation is of paramount importance. In this paper distributed implementations ... -
Performance evaluation of batch encodings in HEVC using slice level parallelism
(2016)HEVC has emerged as the new video standard to replace H.264/AVC. Although the new standard is able to achieve significantly higher compression ratios compared to the older one, it entails high computational demands. To ... -
Real time vision-based measurements for quality control of industrial rods on a moving conveyor
(2018)This work proposes a fully automated approach for vision-based quality control of manufactured metal rods. The proposed approach is able to detect the main axis of the rod and calculate its curvature, versus specifications. ... -
Review and comparative analysis of parallel video encoding techniques for VVC
(2020)In this paper we review and summarize research results concerning video encoding parallelization, with a primary focus on medium and fine grained methods that operate at block or inner block levels. Taxonomies are illustrated ... -
Scalable 3D video streaming over P2P networks with playback length changeable chunk segmentation
(2015)3D video distribution over P2P networks has been thought as a promising way for 3D video entering home. The convergence of scalable 3D video coding and P2P streaming can provide diverse 3D experiences for heterogeneous ... -
Scheduling Video Transcoding Jobs in the Cloud
(2018)Video transcoding is the process of producing from an original (already encoded) input video sequence, multiple output sequences, each at potentially different bitrate, resolution and/or format. Transcoding is essential ... -
Slice-based parallelization in HEVC encoding: Realizing the potential through efficient load balancing
(2017)The new video coding standard HEVC (High Efficiency Video Coding) offers the desired compression performance in the era of HDTV and UHDTV, as it achieves nearly 50% bit rate saving compared to H.264/AVC. To leverage the ... -
Tile Based Wavefront Parallelism in HEVC
(2020)High Efficiency Video Coding (HEVC) was developed to tackle the 4K resolution era, achieving up to 50% more compression efficiency (for the same video quality) compared to its predecessor H.264/AVC. However, this performance ... -
Video-surveillance and context aware system for activity recognition
(2010)Fall detection is the main issue in design an AAL system for elderly. This paper describes an algorithm for vision and audio fall detection. The main problem with video surveillance is the distinction of a fall from similar ...
