This paper proposes a low bit-rate video coding scheme based on combination of motion compensation and waveform coding. In order to realize appropriate bit-allocation to both motion compensation and waveform coding according to the structural properties of video signals, we employ matching pursuits

with one range image at a time, we first scan-convert it to a distance function, then combine this with the data already acquired using a simple additive scheme. To achieve space efficiency, we employ a run-length encoding of the volume. To achieve time efficiency, we resample the range image to align

accompanied by many software and hardware errors. In this paper a hybrid testbed approach is introduced which seamlessly combines real 802.15.4 deployments with real-time simulations based on OMNeT++. The integration of a simulation tool in a testbed bears good prospects and reduces costs since extensive

The goal of the proposed research is to enhance group experiences in a museum by: (1) intelligent distribution of information across several devices, allowing members of a group to follow a public presentation while their personal interests are addressed through individual annotations on a private device, and (2) navigation support of the whole group, by finding a route through the museum that maximizes the interests of all group members and helps to mutually explore and uncover most of the relevant topics related to a cultural heritage site. 1

Abstract. The transactional memory programming paradigm is gaining momentum as the approach of choice for replacing locks in concurrent programming. This paper introduces the transactional locking II (TL2) algorithm, a software transactional memory (STM) algorithm based on a combination of commit

of such metacomputing applications. Unfortunately, none of them addresses seamless sequential, multithreaded and distributed computing, i.e. the execution of the same application on a multiprocessor shared-memory machine as well as on a network of workstations, or on any hierarchical combination of both. In this paper

Abstract. Image stitching is used to combine several individual images having some overlap into a composite image. The quality of image stitching is measured by the similarity of the stitched image to each of the input images, and by the visibility of the seam between the stitched images. In order

the constituent images so that they can be combined as seamlessly as possible; and gradient-domain fusion, a process based on Poisson equations, to further reduce any remaining visible artifacts in the composite. Also central to the framework is a suite of interactive tools that allow the user to specify a

implemented in which the physical world can be invisibly and seamlessly augmented with electronic tags in order to connect physical objects with virtual representations or computational functionality. We demonstrate the utility of linking physical objects to electronic services and actions that are naturally

, and software libraries. We also expect that future users are likely to own many types of devices. Depending on users ’ changing situations and environments, they may choose to switch from one type of device to another that brings the best combination of application functionality and device mobility (size
