Special Issue Information

Dear Colleagues,

This Special Issue, entitled “Multimedia in Radio Communication and Teleinformatics”, is dedicated to original articles and extended versions of papers published in the context of the “Conference of Radiocommunications and ICT (KRiT)”.

This Special Issue focuses on the latest research and applications in multimedia telecommunications networks. With the rise of the Internet of Things (IoT) and other emerging technologies, there is a growing need for efficient and reliable multimedia radio transmission in various settings. This includes local multimedia WLAN wireless networks, multimedia wireless sensor and ad hoc networks, and multimedia sea, air and satellite radio communication.

In addition, this Special Issue aims to explore multimedia systems and radio communication networks for special applications, such as radio and television systems and networks. The use of multimedia techniques, architectures and telecommunications protocols is also of great interest.

The integration of multimedia systems and ICT networks, as well as multimedia applications and services on the Internet, pose significant challenges related to quality of service (QoS), quality of experience (QoE) and reliability. Therefore, optimization and artificial intelligence algorithms are needed to enhance multimedia telecommunications networks.

Solutions for multimedia systems and cloud networks are also a priority, along with ensuring the security of multimedia networks and ICT systems through cryptography and cybersecurity mechanisms. Network aspects of the Internet of Things multimedia systems and measurements in multimedia telecommunications will also be discussed.

Finally, legal, economic and social aspects in multimedia telecommunications will be examined, as they play an essential role in shaping the development and deployment of these technologies.

Topics may include, but are not limited to, the following:

  • Multimedia radio transmission in Internet of Things systems;
  • Local multimedia WLAN wireless networks;
  • Multimedia wireless sensor and ad hoc networks;
  • Multimedia sea, air and satellite radio communication;
  • Multimedia systems and radio communication networks for special applications;
  • Radio and television systems and networks;
  • Multimedia techniques;
  • Multimedia architectures and telecommunications protocols;
  • Multimedia systems and ICT networks;
  • Multimedia applications and services on the Internet;
  • Quality of services and reliability of multimedia ICT networks;
  • Optimization and artificial intelligence algorithms in multimedia telecommunications networks;
  • Solutions for multimedia systems and cloud networks;
  • Security of multimedia networks and ICT systems;
  • Cryptography and cybersecurity mechanisms in multimedia;
  • Network aspects of multimedia systems of the Internet of Things;
  • Measurements in multimedia telecommunications;
  • Legal, economic and social aspects in multimedia telecommunications.

We look forward to receiving your contributions.

A study of video quality perceived by user (Quality of Experience, QoE) was conducted with an examination of whether and how the order and structure of the video sequence presentation affects subjective assessment. For this purpose, the influence of content variability/repeatability, the quality of the preceding sequence, and the sequence order were analyzed. Observations on the correlation of QoE with the micro-structure of sequence presentation are described, which can be the basis for hypotheses of the dependence of QoE assessment on the abovementioned factors. The observed relationships regarding the influence of the number of video repetitions and the impact of the predecessor’s quality on subjective evaluation are consistent with research work on the influence of the order/arrangement and structure of research stimuli on the results of subjective evaluations. Areas for further research are indicated, including relating obtained results in the area of QoE to other cognitive sciences, such as psychological, medical, and economic sciences. Full article

Solutions for emotion recognition are becoming more popular every year, especially with the growth of computer vision. In this paper, classification of emotions is conducted based on images processed with convolutional neural networks (CNNs). Several models are proposed, both custom and transfer learning types. Furthermore, combinations of them as ensembles, alongside various methods of dataset modification, are presented. In the beginning, the models were tested on the original FER2013 dataset. Then, dataset filtering and augmentation were introduced, and the models were retrained accordingly. Two methods of emotion classification were examined: a multi-class classification, and a binary classification. In the former approach, the model returns the probability for each class. In the latter, separate models for each single class are prepared, together with an adequate dataset based on FER2013. Each model recognizes a single emotion from the others. The obtained results and a comparison of the applied methods across different models is presented and discussed. Full article
