This paper provides a technical overview of newly added in-loop filtering technique, sample adaptive offset (SAO), in High Efficiency Video Coding (HEVC). The key idea SAO is to reduce distortion by first classifying reconstructed samples into different categories, obtaining an for each category, and then adding the category. category properly calculated at encoder explicitly signaled decoder reducing effectively, while classification performed both saving side information significantly. To...
This paper overviews the motion vector coding and block merging techniques in Versatile Video Coding (VVC) standard developed by Joint Experts Team (JVET). In general, inter-prediction VVC can be classified into two major groups: "whole block-based inter prediction" "subblock-based prediction". this paper, we focus on for whole prediction. As its predecessor, High Efficiency (HEVC), prediction is represented adaptive (AMVP) mode or merge mode. Newly introduced features purely AMVP include...
This paper describes a video coding technology proposal submitted by MediaTek in April 2018 response to joint call for proposals (CfP) issued ITU-T VCEG and ISO/IEC MPEG. The uses the conventional block-based hybrid approach with breakthrough design of block structure, substantial improvements tools, new inventions loop filtering techniques. First, structure is designed using highly flexible partitioning scheme, where each tree unit picture split into multiple units (CUs) recursive...
Common examinations for diagnosing obstructive sleep apnea (OSA) are polysomnography (PSG) and home testing (HSAT). However, both PSG HSAT require that sensors be attached to a subject, which may disturb their affect the results. Hence, in this study, we aimed verify wireless radar framework combined with deep learning techniques screen risk of OSA home-based environments. This study prospectively collected parameters from 80 participants over 147 nights using 24-GHz framework. The proposed...
We present a novel hardware architecture supporting diamond search and fast full for block matching motion estimation. It can handle irregular data flow of these algorithms without pipeline bubbles, reduce computation duplicated positions. The proposed needs preprocessing with small amount computational power while performing is suitable the platform-based video coding system. While mode be applied real-time requirements, we choose mode, which adapts processing cycles to picture contents...
Abstract Cities worldwide have planned and implemented large‐scale wireless mesh network (WMN) deployments. These deployments are expected to provide broadband mobile access the Internet at a low cost user. This paper considers fairness problem affecting nodes in multihop WMNs. Many existing approaches coping with unsuitable because they necessitate modifications IEEE 802.11 MAC protocol or node queueing operations. Such require change hardware/firmware every WMN. Thus, these less favorable...
For the operation and aerial photography of UAV, it is important to identify blindspots observe details on ground. But limited by camera resolution, small or fuzzy objects can not be effectively observed. Therefore, repairment high-definition images has become one problems solved. In recent years, development deep learning method solved loss blurring images, but because difficulties in training speed calculation only used with low-pixel images. we propose a for superimposing first content...
For MPEG-4 texture coding, an efficient Interleaving DCT and IDCT Schedule (IDIS) is proposed. With this scheme, the DCT-Q-IQ-IDCT coding loop can be implemented with no buffers least latency, which in turn makes number of for MC a minimum two. Also by characteristics IDIS, substructure sharing technique applied DC/AC prediction Q IQ to reduce hardware cost further. All functions are integrated comprise block engine operations video standard. encoding sequence 720/spl times/480 at 30 fps,...
In this paper, we study strategies in incremental planning for ordering and grouping subproblems partitioned by the subgoals of a problem. To generate rich set partial orders subproblems, propose an algorithm based on relaxed plan that ignores delete lists. The new considers both initial goal states can effectively order such way greatly reduces number invalidations during planning. We have also considered trade-offs between granularity subgoal sets complexity solving overall efficient...
The use of multihop wireless networks based on the 802.11 technology has been growing. primary advantages this approach are mature and ease deployment. However, fairness property provided by DCF (distributed coordination function) in a single hop environment shown to be non-existent environment. For example, backhaul network, nodes that more hops away from gateway starved closer gateway. This paper focuses study when TCP flows carried over networks. By not modifying lower layer protocols,...
This paper presents evaluation results of Low Complexity Enhancement Video Codec (LCEVC) using its reference implementation (LTM-5.4.1) when combined with HEVC (HM-16.25) and VVC (VTM-19.0) as base layer codecs. Tests were performed for 4K content, following JVET Random Access (RA) Common Testing Conditions (CTC). The anchor is the result single coding, i.e., encoding videos by VTM or HM only, test codec, which encodes quarter-resolution version layer, followed enhancement coded L TM-5.4.1,...

Most bandit algorithm designs are purely theoretical. Therefore, they have strong regret guarantees, but also often too conservative in practice. In this work, we pioneer the idea of design by minimizing empirical Bayes regret, average over problem instances sampled from a known distribution. We focus on tractable instance problem, confidence interval and posterior width tuning, propose an efficient for solving it. The tuning is analyzed evaluated multi-armed, linear, generalized linear...
