    Abstract: A system for storing target images for object recognition predicts a querying performance for the target image if the target image were included in a search tree of a database. The search tree has a universal search tree structure that is fixed so that it does not change with the addition of new target images. The target image is selected for inclusion or exclusion in the search tree based on the based on the querying performance, wherein the fixed tree structure of the search tree does not change if inclusion of the target image is selected.

    Abstract: A multi-user augmented reality (AR) system operates without a previously acquired common reference by generating a reference image on the fly. The reference image is produced by capturing at least two images of a planar object and using the images to determine a pose (position and orientation) of a first mobile platform with respect to the planar object. Based on the orientation of the mobile platform, an image of the planar object, which may be one of the initial images or a subsequently captured image, is warped to produce the reference image of a front view of the planar object. The reference image may be produced by the mobile platform or by, e.g., a server. Other mobile platforms may determine their pose with respect to the planar object using the reference image to perform a multi-user augmented reality application.

    Abstract translation: 多用户增强现实（AR）系统通过即时生成参考图像而无需先前获取的公共参考。 通过捕获平面物体的至少两个图像并使用图像来确定第一移动平台相对于平面对象的姿势（位置和方位）来产生参考图像。 基于移动平台的方向，可以将平面对象的图像（其可以是初始图像之一或随后的拍摄图像）扭曲，以产生平面对象的前视图的参考图像。 参考图像可以由移动平台或者例如由服务器产生。 其他移动平台可以使用参考图像来确定其相对于平面对象的姿态来执行多用户增强现实应用。

    Abstract: In several aspects, an electronic device and method index a repository of N documents by W words, by not storing between queries, N*W numbers that are specific to each word i and each document j, normally used to compute a score of relevance to a query, of each document j. Instead, the electronic device and method generate the N*W word-specific-document-specific numbers dynamically at query time, based on a set of W numbers corresponding to the W words, and one or more sets (e.g. x sets) of N numbers corresponding to the N documents. Query-time generation of word-specific-document-specific numbers reduces memory otherwise required, e.g. to store these numbers. Hence, in certain aspects W+xN numbers are maintained between queries, and these numbers are changed incrementally when a new document is added to the set or an existing document is removed. Maintaining W+xN numbers reduces processing otherwise required, to start from scratch.

    Abstract translation: 在几个方面，电子设备和方法通过W字来索引N个文档的存储库，通过不存储查询之间的N * W数字，每个单词i和每个文档j都是特定的，通常用于计算与 每个文件的查询j。 相反，电子设备和方法基于与W字相对应的一组W数字，以及一个或多个（例如x集）的N个集合（例如x集合），在查询时间动态地生成N * W个字特定文档特定号码 与N个文件相对应的数字。 单词特定文档特定号码的查询时间生成减少了所需的内存，例如。 存储这些数字。 因此，在某些方面，在查询之间维护W + xN个数，并且当将新文档添加到集合或删除现有文档时，这些数字将逐渐更改。 维护W + xN数字可以减少否则需要的处理，从头开始。

    Abstract: Systems and methods share context information on a neighbor aware network. A method for communicating data in a wireless communications network is disclosed. The method includes receiving, by a device, a first message from a station, decoding the message to determine service information, the service information identifying a service provided by the station, generating a second message, wherein the second message is generated to indicate the service provided by the station and service information of the device, and transmitting, by the device, the second message to a remote station.
