Abstract: Media tagging is significantly improved by fusing subjective, user-specific tags with collaborative, community-based tags. Users share multimedia metadata tags in a network of users, to improve automatic tag generation for personal multimedia collections without compromising media privacy. In one method, a combined set of annotation tags is suggested to a user, for use in annotating a given media file. The combined set includes a first set drawn from a private, user-specific repository, and a second set drawn from a public, shared repository. In each case, determining which tags are suggested involves computing similarities between an attribute vector associated with the media file being tagged and attribute vectors associated with the tags. An attribute vector is a set of values representing given types of contextual metadata. The similarity determinations may be weighted according to user-specific and shared weights, and these weightings can be adapted to reflect user and community preferences.

Abstract: Methods (700, 900) for providing information from an encoder (220) to a decoder (230) concerning a spatial validity range, at which view synthesis of an image at a virtual camera position can be performed with sufficient visual quality, based on a view of at least one real camera (210-1) comprised in a set of real cameras (210-1, 210-2, 210-3, 210-4). The methods (700, 900) comprises determining (701) the spatial validity range of the at least one real camera (210-1), which spatial validity range specifies for the decoder (230) what information to use for synthesising the image of the virtual camera position. Also, the determined (701) spatial validity range is transmitted (706) to the decoder (230).

Abstract: A method and arrangement for enabling purchase of an item offered by an item provider. The content of a communication session in which a user takes part at a communication network is analysed (200). Based on the content, one or more user profiles are created (202). Each profile is divided in a plurality of categories. The categories may represent preferences, plans, and other information analysed from the content of the communication session. Purchase offers regarding provided items are received (204) from the item provider by the purchase unit. The items are matched (206) with at least one user profile by the purchase unit, and the purchase offers regarding the matching item is conveyed (208) to the user. By creating and/or updating user profiles based on the content of a user's communication sessions, the user can be offered more personalised purchase offers, without being offered generic purchase offers.

Abstract: The embodiments of the present invention relates to a method and a processor for representing a 3D scene. In the method, one 3D component of the 3D scene to be represented, captured at least three different views (v1,v2,v3) is projecting to a predefined view (vF). A value associated with each projected view regarding the 3D component is then determined and consistency among the projected views regarding the 3D component is detected. Moreover, a consistency value regarding the 3D component is determined based on the determined values associated with the respective projected view, and the determined values are replaced by the determined consistency value on at least one of the three projected 3D components.

Abstract: The embodiments of the present invention relates to a method and system for classifying media. The classification is achieved by using annotation ontolgies and by associating bottom level concepts of the annotation ontology tree with explanatory representation data of a selected representation domain and then comparing the explanatory representation data with transformation of the media in the selected representation domain. In this way tags can be generated which corresponds to bottom level concepts of the ontology tree which corresponds to explanatory representation data which can be found in the transformed media.

Abstract: A method and arrangements at a multimedia distribution network for estimating a present user constellation of a household are suggested. A sequence of textual descriptors that are associated with a multimedia sequence that is presently provided to the household is monitored. By acquiring a set of parameters of a statistical model that is based on textual descriptors that have previously been provided to the household, and by estimating a present user constellation by correlating the sequence of textual descriptors with the parameters of the statistical model, the estimated information may be used for customization of content that is provided to the household.
