摘要： Images in a database or collection of images are each divided into multiple partitions with each partition corresponding to an area of an image. The partitions in an image may overlap with each other. Min-hash sketches are generated for each of the partitions and stored with the images. A user may submit an image and request that an image that is a partial match for the submitted image be located in the image collection. The submitted image is similarly divided into partitions and min-hash sketches are generated from the partitions. The min-hash sketches are compared with the stored min-hash sketches for matches, and images having partitions whose sketches are matches are returned as partial matching images.
摘要翻译：数据库或图像集合中的图像被分成多个分区，每个分区对应于图像的区域。图像中的分区可能会彼此重叠。为每个分区生成最小散列草图，并与图像一起存储。用户可以提交图像并请求作为所提交图像的部分匹配的图像位于图像集合中。提交的图像类似地划分为分区，并且从分区生成最小哈希草图。将最小哈希草图与存储的最小哈希草图进行比较，并将具有其草图匹配的分区的图像作为部分匹配图像返回。

摘要： Trusted user accounts of an application provider are determined. Graphs, such as trees, are created with each node corresponding to a trusted account. Each of the nodes is associated with a vouching quota, or the nodes may share a vouching quota. Untrusted user accounts are determined. For each of these untrusted accounts, a trusted user account that has a social networking relationship is determined. If the node corresponding to the trusted user account has enough vouching quota to vouch for the untrusted user account, then the quota is debited, a node is added for the untrusted user account to the graph, and the untrusted user account is vouched for. If not, available vouching quota may be borrowed from other nodes in the graph.
摘要翻译：确定应用程序提供程序的可信用户帐户。使用与受信任帐户相对应的每个节点来创建诸如树之类的图形。每个节点都与一个备份配额相关联，或者节点可以共享一个备份配额。不信任的用户帐户被确定。对于每个这些不受信任的帐户，确定具有社交网络关系的可信用户帐户。如果与受信任用户帐户相对应的节点具有足够的备用配额来保证不受信任的用户帐户，则会将配额扣除，为图中不可信任的用户帐户添加一个节点，并为不受信任的用户帐户进行验证。如果不是，可以从图中的其他节点借用可用的支票配额。

摘要： A data partitioning plan is automatically generated that—given a data-parallel program and a large input dataset, and without having to first run the program on the input dataset—substantially optimizes performance of the distributed execution system that explicitly measures and infers various properties of both data and computation to perform cost estimation and optimization. Estimation may comprise inferring the cost of a candidate data partitioning plan, and optimization may comprise generating an optimal partitioning plan based on the estimated costs of computation and input/output.

摘要： The present invention uses invisible junctions which are a set of local features unique to every page of the electronic document to match the captured image to a part of an electronic document. The present invention includes: an image capture device, a feature extraction and recognition system and database. When an electronic document is printed, the feature extraction and recognition system captures an image of the document page. The features in the captured image are then extracted, indexed and stored in the database. Given a query image, usually a small patch of some document page captured by a low resolution image capture device, the features in the query image are extracted and compared against those stored in the database to identify the query image. The present invention also includes methods for recognizing and tracking the viewing region and look at point corresponding to the input query image. This information is combined with a rendering of the original input document to generate a new graphical user interface to the user. This user interface can be displayed on a conventional browser or even on the display of an image capture device.

摘要： A system and a method are disclosed for generating video. Object information is received. A path of motion of the object relative to a reference point is generated. A series of images and ground for a reference frame are generated from the ground truth and the generated path. A system and a method are disclosed for generating an image. Object information is received. Image data and ground truth may be generated using position, the image description, the camera characteristics, and image distortion parameters. A positional relationship between the document and a reference point is determined. An image of the document and ground truth are generated from the object information and the positional relationship and in response to user specified environment of the document.
