Multimedia coding technology, after about 20 years of active research, has delivered a rich variety of different and complex coding algorithms. Selecting an appropriate subset of these algorithms would, in principle, enable a designer to produce the codec ...
Analogue wireless cameras have been employed for decades, however they have not become an universal solution due to their difficulties of set up and use. The main problem is the link robustness which mainly depends on the requirement of a line-of-sight vie ...
With the spread of computer technology into the artistic fields, new application scenarios for computer-based applications of symbolic music representation (SMR) have been identified. The integration of SMR in a versatile multimedia framework such as MPEG ...
We propose a smart camera which performs video analysis and generates an MPEG-7 compliant stream. By producing a content-based metadata description of the scene, the MPEG-7 camera extends the capabilities of conventional cameras. The metadata is then direc ...
We present an encoding framework which exploits semantics for video content delivery. The video content is organized based on the idea of main content message. In the work reported in this paper, the main content message is extracted from the video data th ...
We present a quality management method for multimedia applications. The method takes as input an application software composed of actions. The execution times of actions are unknown increasing functions of quality level parameters. The method allows the co ...
This paper presents a new technique for perfect reconstruction non-uniform QMF decomposition developed to increase efficiency of a generic wide-band audio coding system based on Frequency Domain Linear Prediction (FDLP). The base line FDLP codec, operating ...
The paper presents a methodology and supporting tools for developing component-based embedded systems running on resource-limited hardware platforms. The methodology combines two complementary component frameworks in an integrated tool chain: BIP and Think ...
There is a clear trend of future embedded systems in moving toward wireless, multimedia, multi-functional and ubiquitous applications. This emerges new challenges in the existing solutions on performance, power, flexibility and costs, calling for innovatio ...
Expressive facial animation synthesis of human like characters has had many approaches with good results. MPEG-4 standard has functioned as the basis of many of those approaches. In this paper we would like to lay out the knowledge of some of those approac ...
