摘要： A system for identifying individuals in digital images and for providing matching digital images is provided. A set of images that include faces of known individuals is received. Faces are detected in the images and facial components are identified in each face. Visual words corresponding to the facial components are generated, stored, and associated with identifiers of the individuals. At a later time, a user may provide an image that includes the face of one of the known individuals. Visual words are determined from the face of the individual in the provided image and matched against the stored visual words. Images associated with matching visual words are ranked and presented to the user.
摘要翻译：提供了一种用于识别数字图像中的个体并提供匹配的数字图像的系统。接收包括已知个人面孔的一组图像。在图像中检测到面部，并且在每个面部中识别面部组件。对应于面部组件的视觉词被生成，存储并与个人的标识符相关联。在稍后的时间，用户可以提供包括已知个体之一的脸部的图像。视觉词是从提供的图像中的个体的脸部确定的，并且与存储的视觉词匹配。与匹配的视觉词相关联的图像被排序并呈现给用户。

摘要： Methods are disclosed for finding images from a large corpus of images that at least partially match a query image. The present method makes use of feature detectors to bundle features into local groups or bundles. These bundled features are repeatable and much more discriminative than an individual SIFT feature. Equally importantly, the bundled features provide a flexible representation that allows simple and robust geometric constraints to be efficiently enforced when querying the index.
摘要翻译：公开了用于从至少部分匹配查询图像的大图像的图像中发现图像的方法。本方法利用特征检测器将特征分组到本地组或束中。这些捆绑功能是可重复的，比单独的SIFT功能更具歧视性。同样重要的是，捆绑功能提供了灵活的表示，允许在查询索引时有效执行简单和强大的几何约束。

摘要： Methods and computer-storage media having computer-executable instructions embodied thereon that facilitate refining query results using visual cues are provided. Query results are determined in response to an indication of a user query. One or more groups of query results are generated from the query results based on categories of query results that share similar features. Visual cues are associated with each of the query result groups. Visual cues, in association with query result groups, are presented to a user. Query results associated with a selected visual cue may be presented to a user. A refined user query may be generated based on a selected visual cue.

摘要： A flash-based strategy is used to separate foreground information from background information within image information. In this strategy, a first image is taken without the use of flash. A second image is taken of the same subject matter with the use of flash. The foreground information in the flash image is illuminated by the flash to a much greater extent than the background information. Based on this property, the strategy applies processing to extract the foreground information from the background information. The strategy supplements the flash information by also taking into consideration motion information and color information.

摘要： A method for creating an optimized gradient mesh of a vector-based image from a raster-based image. In one implementation, a set of boundaries for an object on a raster-based image may be received. An initial gradient mesh of the object may be created. A residual energy between the object on the raster-based image and a rendered initial gradient mesh may be minimized to generate an optimized gradient mesh.
