TL;DR: In this paper, the authors propose a handoff of application-specific functionality with a network layer-Ievel handoff to enable the mobile terminal to seamlessly execute an application that utilizes the media content from a content source that is supporting the mobile node before the handoff.
Abstract: The present invention provides a relocation of an application-specific functionality for an application that a mobile terminal (mobile node) is executing. Entities that may provide application-specific functionalities that assist the application include a location-based server (that may be associated with a supplementary service provider functionality), a transcoder proxy, and a security gateway. The relocation of the application-specific functionality with a network layer-Ievel handoff enables the mobile terminal to seamlessly execute an application that utilizes the media content from a content source that is supporting the mobile terminal before the handoff. Subsequent to the handoff, the mobile terminal registers with a current access router in order to inform the current access router about application context information. In the exemplary embodiments, the access routers and the content source support the discovery of an entity that can support the application-specific functionality and the configuration of the application-specific functionality after the handoff.

TL;DR: In this article, a photographic system involves the collection of data from a scene, e.g., a visitor attraction site, that is capable of interactive communication with a user, and the user communicates with the attraction site through a camera capable of communication with the site.
Abstract: A photographic system involves the collection of data from a scene, e.g., a visitor attraction site, that is capable of interactive communication with a user. The attraction site stores content data related to the site, and the user communicates with the attraction site through a camera capable of communication with the site. Besides capturing an image associated with the site, the camera stores predetermined personality data that relates an interest of the user to at least a portion of the content data and includes means for transferring the personality data to the attraction site. The camera further includes means for receiving and displaying the portion of the content data from the attraction site, and a user interface for selecting from the displayed content data that part which the user wants to keep. In this manner, information relevant to a user's interests about a photographed item can be easily requested, accessed and stored with the specific pictures that the user has captured.

TL;DR: In this paper, a processing arrangement consisting of at least one data processing unit (1), and a communication unit (2) connected to the data processing units (1) is proposed, in which a plurality of addresses may be assigned to the communication unit.
Abstract: The invention proposes a processing arrangement (to be used in a communication device, for example) , wherein the processing arrangement comprises at least one data processing unit (1), and a communication unit (2) connected to the data processing unit (1) , wherein the at least one data processing unit (1) is configured to perform data processing and the communication unit (2) is configured to provide a connection to the external, a packet transport control is used for the connection to the external, in which a plurality of addresses may be assigned to the communication unit (2), and the communication unit and the data processing unit comprise delivering means (13, 23) for delivering packets, which are to be delivered between the data processing unit (1) and the external, via an encapsulated connection (3) between the data processing unit and communication unit. The invention also proposes a corresponding communication method.

TL;DR: In this paper, the authors propose a system and method for determining charges for use of network service connections, which includes nodes which facilitate the transfer of information between source and destination locations.
Abstract: A system and method for determining charges for use of network service connections. The network includes nodes which facilitate the transfer of information between source and destination locations. When a connection is established with a node, a billing cell is transmitted to the node over the connection which contains billing and connection information. Data cells are transmitted over the same connection subsequent to the billing cell. A terminate billing cell or conventional means may be used to drop the connection when the connection is no longer needed. The node computes the cost of using the connection based on the billing and connection information copied from the billing cell, and may also consider the connection time and the amount of data transferred over the connection. Upon establishing a subsequent connection with another node, the previous node transmits the billing cell to the new node which copies the billing cell content and, after receiving the data cells over the new connection, performs similar connection usage computations. This process is repeatded by each of the nodes involved in the transfer of information between the source and destination. The nodes transmit their respective charging information to a network billing system which generates a final bill that is forwarded to the user. The billing cell may be transmitted from the destination back to the source to verify proper operation of the billing procedure. Fixed rate and variable rate billing schemes may be implemented and augmented as needed by each network operator.

TL;DR: This work review and categorize algorithms for contentaware image retargeting, i.e., resizing an image while taking its content into consideration to preserve important regions and minimize distortions, as it requires preserving the relevant information while maintaining an aesthetically pleasing image for the user.
Abstract: Advances in imaging technology have made the capture and display of digital images ubiquitous. A variety of displays are used to view them, ranging from high-resolution computer monitors to low-resolution mobile devices, and images often have to undergo changes in size and aspect ratio to adapt to different screens. Also, displaying and printing documents with embedded images frequently entail resizing of the images to comply with the overall layout. Straightforward image resizing operators, such as scaling, often do not produce satisfactory results, since they are oblivious to image content. In this work, we review and categorize algorithms for contentaware image retargeting, i.e., resizing an image while taking its content into consideration to preserve important regions and minimize distortions. This is a challenging problem, as it requires preserving the relevant information while maintaining an aesthetically pleasing image for the user. The techniques typically start by computing an importance map which represents the relevance of every pixel, and then apply an operator that resizes the image while taking into account the importance map and additional constraints. We intend this review to be useful to researchers and practitioners interested in image retargeting.
