Abstract: A computing device and method are provided for accelerating the coarse relocalization process of the computing device by generating a current fingerprint using signal data detected by sensors, statistically analyzing the current fingerprint for proximity to candidate fingerprints in fingerprint data to generate a ranked list, and subsequently retrieving map data corresponding to the closest matching fingerprints in the ranked list. The computing device may comprise a processor, a memory operatively coupled to the processor, and a fingerprint program stored in the memory and executed by the processor.

Abstract: Systems, apparatuses and methods to provide image data, augmented with related data, to be displayed on a mobile computing device are disclosed. An example mobile device includes a camera to provide images of a scene from different angles to a server, at least one sensor to sense a position and an orientation of the camera, and a screen to present augmented reality data over the scene based on the position and the orientation of the camera and on a three-dimensional representation of the scene based on the images.

Abstract: Mixed-reality systems are provided for using anchor graphs within a mixed-reality environment. These systems utilize anchor vertexes that comprise at least one first key frame, a first mixed-reality element, and at least one first transform connecting the at least one first key frame to the first mixed-reality element. Anchor edges comprising transformations connect the anchor vertexes.

Abstract: Embodiments of the invention relate to systems, apparatuses and methods to provide image data, augmented with related data, to be displayed on a mobile computing device. Embodiments of the invention display a live view augmented with information identifying an object amongst other objects. Embodiments of the invention may utilize other related data, such as 3D point cloud data, image data and location data related to the object, to obtain a specific location of an object within the live view. Embodiments of the invention may further display a live view with augmented data three-dimensionally consistent with the position and orientation of the image sensor of the mobile computing device.

Abstract: A method, apparatus and computer program product may be provided for generating a plurality of compressed feature descriptors that can be represented by a relatively small number of bits, thereby facilitating transmission and storage of the feature descriptors. A method, apparatus and computer program product may also be provided for permitting a compressed representation of a feature descriptor to be compared with a plurality of compressed representations of feature descriptors of respective predefined features. By permitting the comparison to be performed utilizing compressed representations of feature descriptors, a respective feature descriptor may be identified without having to first decompress the feature descriptor, thereby potentially increasing the efficiency with which feature descriptors may be identified.

Abstract: The disclosure relates to a method in which one or more local descriptors relating to an interest point of an image are received. A global descriptor is determined for the image on the basis of the one or more local descriptors; and the global descriptor is compressed. The disclosure also relates to an apparatus comprising a processor and a memory including computer program code, and storage medium having stored thereon a computer executable program code for use by an apparatus.

Abstract: Various methods are described for improving the compression of location information during a visual search. One example method may comprise identifying one or more features of a source query image for a visual search. The method may further comprise generating a histogram map comprising one or more histogram bins, wherein the histogram map represents the location of the one or more features of the source query image. Additionally, the method may comprise generating a context for at least one of the one or more histogram bins, wherein the context comprises a first context value based on information related to one or more neighboring bins located a first distance from the respective histogram bin and a second context value based on information related to one or more neighboring bins located a second distance from the respective histogram bin. Similar and related methods, apparatuses, and computer program products are also provided.

Abstract: Methods and apparatuses are provided for facilitating face image analysis. A method may include determining a histogram-based face descriptor for each of a plurality of regions of a face image. The method may further include compressing the histogram-based face descriptors to generate a plurality of compressed face descriptors describing the plurality of regions of the face image.
