In this paper, we present precise time and energy models for an intra-only HEVC video encoder. These models are a step forward to understand and estimate the computational complexity and energy demands of an HEVC encoder, which in turn opens the path to finely tuning the computational resources that are dedicated to this purpose. Our models estimate the complexity and energy consumed by the HEVC encoder,...
HEVC and VP9 are the current state-of-the-art in video compression, thus, it is expected that in the near future these new codecs will replace their predecessors. However, the process of converting video contents compressed with one standard to those using another standard is highly computationally expensive, since a priori the video contents must be decompressed and compressed with the target video...
In this paper we evaluate four mainstream video encoders: H.264/MPEG-4 Advanced Video Coding, Google's VP8, High Efficiency Video Coding, and Google's VP9, studying conventional figures-of-merit such as performance in terms of encoded frames per second, and encoding efficiency in both PSNR and bit-rate of the encoded video sequences. Additionally, two platforms equipped with a large number of cores,...
Our objective was to determine if the phycobiliproteins of Arthrospira (Spirulina) maxima protect renal cells against mercury-caused oxidative stress and cellular damage in the kidney. We used 40 male mice that were assigned into eight groups: (1) a control group that received 100mM phosphate buffer (PB) ig and 0.9% saline ip, (2) PB+HgCl 2 (5mg/kg ip), (3) PB plus phycobiliproteins (100mg/kg...
H.264/AVC applies a complex mode decision technique that has high computational complexity in order to reduce the temporal redundancies of video sequences. Several algorithms have been proposed in the literature in recent years with the aim of accelerating this part of the encoding process. Recently, with the emergence of many-core processors or accelerators, a new approach can be adopted for reducing...
When we study a subject like ldquointroduction to computer programingrdquo with languages like C or C++, some aspects may be considered boring by students. On the one hand, the programs we present often have an ugly aspect due to the fact that we use the command line interface (console) to communicate with user, and on the other hand, these programs tend to solve very simple problems that are usually...
