High-dynamic-range (HDR) technology is an emerging video technology that allows displays to produce a higher range of luminance to better approximate the range of brightness perceived by the human eye. However, during the transition to this new technology, not all consumer devices will support the full range of luminance values offered by HDR. In order to also support these devices with lower dynamic...
With the introduction of 4K UHD video and display resolution, questions arise on the perceptual differences between 4K UHD and upsampled HD video content. In this paper, a striped pair comparison has been performed on a diverse set of 4K UHD video sources. The goal was to subjectively assess the perceived sharpness of 4K UHD and downscaled/upscaled HD video. A striped pair comparison has been applied...
In previous work, the authors developed a modular no-reference framework that compresses FASTA files by applying a predict-and-residue method, as used in video coding. We extended this framework with support for Context-Adaptive Binary Arithmetic Coding (CABAC), while at the same time preserving random access functionality and offering support for the full IUB/IUPAC nucleic acid codes alphabet.
High-dynamic-range (HDR) technology allows capturing of video content at a wider range of luminance than low-dynamic-range (LDR) video. The resulting video more closely resembles the scene as perceived by the human eye. However, displays currently support only a limited range of HDR. Therefore, both an HDR version and LDR version of a video should be encoded during content acquisition. This means...
Current algorithms for compressing genomic data mostly focus on achieving high levels of effectiveness and reasonable levels of efficiency, ignoring the need for features such as random access and stream processing. Therefore, in this paper, we introduce a novel framework for compressing genomic data, with the aim of allowing for a better trade-off between effectiveness, efficiency and functionality...
