The paper presents a concept of the videoconferencing system which enables 3D image capturing and reproduction. The full view of collocutors appearance is obtained by using four cameras. Reproduction of 3D video stream is carrying out by using 3D reflection-based display. The 3D video stream processing is fulfilled by a media-server. The software application is based on WebRTC technology. The prototype...
Applications of multimodal information in telecommunications are discussed in this paper. The immersive teleconferencing system intended for registration, transmission and reproduction of multimodal information is discussed. This multimodal information includes 3D graphical data, surround sound data, and environmental data (temperature, air humidity, olfactory data, etc.). The analysis of existing...
This paper presents the method of graphical data steganographic protection based on binary operations applied to both secret data bits and the most significant bits of a cover image in order to define values of the least significant bits to be embedded into the cover according to LSB-steganography approach. The method demonstrates an appropriate level of robustness against attacks. The secret data...
Multimedia has become an ordinary component of modern software and hardware. Sound, graphics, and animation are present at almost every application of both desktop and mobile platforms. However, human senses cover more than two media. Thus, the transition from Multimedia to Mulsemedia (MULtiple SEnsorial MEDIA) is quite natural. Mulsemedia enriches traditional multimedia content with new media objects,...
Existing multimedia systems used in education mostly address only two senses by using two communication channels (visual and audio) of the five human senses (sight, hearing, taste, smell, and touch), limiting the potential efficiency of learning. This paper presents a survey on existing technical opportunities for the development of an immersive learning environment. Four components of the immersive...
The paper presents haptic devices, in particular data gloves, and their possible application in education. A general technique of the development of educational applications using human-computer haptic interaction on the example of 5DT Data Glove is presented as well.
The basic algorithms for both lossless and lossy compression of images are discussed in the paper. The criteria of the contrastive analysis of compression algorithms are chosen. The classes of images are discussed. The results of algorithms realization and testing in MATLAB environment are shown in the diagrams and discussed. The recommendations on future improvement of image compression algorithms...
The central focus of this paper concerns tasks of image processing. In particular it deals with the problem of image classification based on both first-order and second-order statistics. Statistical data obtained in the MATLAB environment are shown in the diagrams and discussed. The principles of image classification are formulated in this paper. The results obtained in the research can be used in...
