In comparison with older standards, High Efficiency Video Coding (HEVC) significantly improves coding efficiency. At the same time, it increases computational complexity of coding and therefore encoding takes a longer time. In this paper, the usage of different implementations of HEVC is proposed where some of them can take advantage of a multicore Central Processing Unit (CPU). The others are accelerated...
The perception of the spatial effect of 3D video is influenced by various factors. One of the most interesting and important factors is the content of the observed video sequence. This factor is relatively little investigated. The content of the scene can be described by particular parameters. The parameters have to describe spatial, temporal, depth and brightness distribution in sequences. We have...
This paper deals with a creation of the RGB-D database by using Microsoft Kinect device. One of the main uses of Kinect is measurement and subsequent creation the so-called depth maps of the 3D scenes. The maps obtained by Kinect can be improved. Existence of databases suitable for the experiment is very important for research. One of the possible research directions is use of infrared version of...
Nowadays, Bluetooth Low Energy (BLE) technology has a great attention in the field of wireless localization techniques, especially in the case of indoor scenarios. Study presented in this paper explores BLE localization performance in indoor scenarios based on a received signal strength (RSS). Firstly, we present a Ray-Launching based application to emulate BLE radio frequency (RF) signal propagation...
Interest in playing/streaming multimedia content in Full High Definition (Full HD) and the upcoming Ultra High Definition (UHD) is rapidly increasing. However, TVs with such resolutions has higher hardware and bandwidth requirements. Hence, advanced compression tools are essential to provide TV services in Full HD and UHD quality. The aim of this paper is to explore coding efficiency performance of...
Nowadays, there are many kinds of technologies to provide multimedia TV content in different formats and picture quality. Three-dimensional (3D) video is one of the next generation TV services with specific features from the video image quality point of view. Naturally, efficient compression tools enabling significant bit rate reduction to ease 3D video distribution are an integral part of any practical...
This paper presents a performance comparison of the two modern video coding standards H.265/HEVC and VP9. For such comparison, the latest available versions of codecs for encoding were used. Comparison is provided by set of objective quality metrics. Comparing of coding efficiency is evaluated for Full HDTV and also for Ultra HDTV. Results indicate a dominance of HEVC encoding algorithm in comparison...
The number of wirelessly connected multimedia devices and different communication standards, supported by these devices, is rapidly increasing. However, the appropriate frequency bands (licensed and unlicensed) for data transmission by these standards are very limited. The rising density of wireless networks and their coexistence in the same or adjacent radio frequency (RF) spectrum can significantly...
