On evaluating the impact of tile partitioning in AV1
(2018)The advent of 4K and 8K resolutions in cameras and TV sets, posed a challenge to Video on Demand (VoD) and live streaming industry since the network overhead compared to FullHD was multiplied. For this reason, new video ... -
On planning the adoption of new video standards in social media networks: a general framework and its application to HEVC
(2017)In recent years, we have witnessed an explosion in the growth of social media networks, powered by the proliferation of handheld smart devices with high processing capabilities and a plethora of sensors including high-resolution ... -
Patterns of blind users' hand movements: The case of typographic signals of documents rendered by eight-dot and six-dot braille code
(2014)The main focus of the present study lies on patterns and characteristics of hand movements when participants with blindness receive typographic meta-data (bold and italic) by touch through a braille display. Patterns and ... -
Performance evaluation of network coding and packet skipping in IEEE 802.15.4-based real-time wireless sensor networks
(2011)In a number of application domains, the volatility of the monitored environment where Wireless Sensor Networks (WSNs) operate engenders timing constraints on the generation, processing, and communication of sensory data. ... -
A Policy-Aware Enforcement Logic for Appropriately Invoking Network Coding
(2016)Network coding has been shown to offer significant throughput benefits over certain wireless network topologies. However, the application of network coding may not always improve the network performance. In this paper, we ... -
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 ... -
Source-level compiler optimizations for high-level synthesis
(2016)With high-level synthesis becoming the preferred method for hardware design, tools that operate on high-level programming languages and optimize hardware output are crucial for successful synthesis. In high-level synthesis, ... -
Towards automatic significance analysis for approximate computing
(2016)Several applications may trade-off output quality for energy efficiency by computing only an approximation of their output. Current approaches to software-based approximate computing often require the programmer to specify ... -
Towards the 8-dot Nemeth Braille code
(2014)In this work, a language-independent design methodology for the systematic development of an 8-dot braille code, has been applied to the Nemeth code. First, we set the design principles: compression, intra-similarity, ...
