Sensors acquire data, and communicate this to an interested party. The arising coding problem is often split into two parts: First, the sensors compress their respective acquired signals, potentially applying the concepts of distributed source coding. Then ...
The concept of event-based behavioral abstraction (EBBA) is shown to facilitate the Design For Testability (DFT) if the set of events is well-chosen. We provide a predefined set of events which, together with linear-time temporal logic, can be used for exp ...
In this paper, we present a no-reference blur metric for images and video. The blur metric is based on the analysis of the spread of the edges in an image. Its perceptual significance is validated through subjective experiments. The novel metric is near re ...
In this project, we investigate the possibility of using the Matching Pursuit algorithm to generate image representations of a pair of correlated images for distributed source coding. We propose to use constrained dictionaries by appropriately selecting ne ...
Based on the notion of event-based behavioral abstraction (EBBA) we specify properties of object-oriented distributed systems in linear time temporal logic. These properties are then observed at system run-time and it is checked whether or not the system v ...
We focus on packet video delivery, with an emphasis on the quality of service perceived by the end-user. A video signal passes through several subsystems, such as the source coder, the network and the decoder. Each of these can impair the information, eith ...
The correct behavior of real-time applications depends not only on the correctness of the results of computations but also on the times at which these results are produced. As a matter of fact, violations of real-time constraints in embedded systems are th ...
