Abstract: Method and systems for generating reference features sets for slices of a reference image. The reference features sets generated from slices enables better object recognition and/or tracking when a camera image only shows a portion of the reference image. Metadata is used to link the reference features set of the original image and of the slices together as belonging to the same object, providing hierarchical relationship information and/or spatial relationship information. An image processing function may be dynamically configured on the basis of whether an object has been successfully detected and the metadata associated with the object.

Abstract: A method for improving the placement of virtual content in augmented reality is disclosed. A reference image of the object to be augmented is analyzed for feature density information. The placement of content is based on the at least one location adjacent to where features are concentrated. Accordingly, the chance of the content interfering with an important part of the object is lowered, and object recognition and/or tracking ability is maintained because there are sufficient features nearby the content to enable object recognition and/or tracking.

Abstract: Disclosed herein is an improved method for providing content associated with barcodes in augmented reality in addition or in combination with providing content associated with target objects in augmented reality. The improved method advantageously provides a augmented reality client that a user may use to view the respective content associated with barcodes and target objects while in camera view to improve usability. Advantageously, the user is not unexpectedly taken out of camera view to view the content associated with the barcode and the user experience provided is consistent between barcodes and target objects. Furthermore, the improved method integrates barcodes and a visualization of the barcode within augmented reality, without disrupting the real-time augmented reality experience.

Abstract: Methods for enabling discovery of content through an augmented reality service provisioning system. A first augmented reality client running on user equipment is provided, wherein the first augmented reality client is embedded in a third-party application, and is configured to allow a user to view at least part of the content offered by the augmented reality service provisioning system. A first input is received from a user through a user interface provided by the user equipment, wherein said first input indicates the user's interest to discover other content. In response to receiving the first input, a request is transmitted to a server in the augmented reality service provisioning system to retrieve relevant content from the other content; wherein the other content is content that the first augmented reality client is not configured to view.

Abstract: Methods for acquiring, generating and displaying ranked points of interests for use in an augmented reality service provisioning system are described. The method for generating such ranked points of interest comprises: receiving feedback information comprising information on users interactions associated with one or more points of interest displayed as selectable graphical indicators on a screen of a mobile device and assigning popularity scores to points of interests identified in said feedback information on the basis of said user interactions; associating a point of interest in a recording list, comprising points of interests sent to one or more mobile devices in said augmented reality service provisioning system, with a popularity score assigned to points of interests identified in said feedback information; and, storing said point of interest and said popularity score in a points of interest database.

Abstract: The invention discloses a system to protect online streaming content by a content provider, by means of access authorization in the network operator's platform. The invention provides a solution to the problem of access authorization for streaming content, that is not exactly known with regards to description and/or location at the moment the access authorization is performed.

Abstract: In a method of retrieving electronic messages the server (2) sends the header and the first N text characters of th message body to the terminal device (1), while holding back any remaining text and any attachments. The server also sends a first flag indicative of any remaining text characters and a second flag indicative of any attachments to the terminal device. The user (5) of the terminal device can then decide to retrieve more text characters and/or any attachments. This phased message retrieval avoids downloading oversized messages and thus saves bandwidth. The terminal device (1) may be a handheld device, for example a mobile telephone or a PDA.
