摘要： A method and system for detecting faces at different views within images that allocates the computational effort based on a prior probability associated with a view is provided. A face detection system determines whether an image contains a face using detectors that are adapted to detect faces at various views and a filter that filters out windows of the image that are provided to a detector based on a prior probability associated with the view of the detector. Each view has an associated prior probability that a face from a collection of real-life home photographs will be at that view. The face detection system allocates increasing computational effort to a detector as the prior probability of its view increases.

摘要： Systems, engines, user interfaces, and methods allow a user to select a group of images, such as digital photographs, and assign to the group of images the name of a person who is represented in each of the images. The name is automatically propagated to the face of the person, each time the person's face occurs in an image. In one implementation, names and associations are shared between a browsing mode for viewing multiple images at once and a viewer mode, for viewing one image at a time. The browsing mode can provide a menu of candidate names for annotating a face in a single image of the viewer mode. Likewise, the viewer mode can provide annotated face information to the browser mode for facilitating name propagation. Identification of a person's face in multiple images can be accomplished not only by finding similarities in facial features but also by finding similarities in contextual features near the face in different images.

摘要： A method and system for cropping an image is provided. The cropping system automatically crops an image by selecting an image template whose condition is best satisfied by the image and then by selecting a cropping of the image that best attains the goal of the selected image template. The cropping system may use a metric or objective function to rate how well a cropping attains the goal of the selected image template. The cropping system may apply various optimization algorithms to identify a cropping that is the best as indicated by the metric. The cropping system can then automatically crop the image based on the identified cropping.

摘要： A method and system for identifying informative links of a web site for use in crawling the web site is provided. A forum crawler analyzes sample web pages of a web forum to identify informative links and then crawls the web forum by following links determined to be informative and not following other links. The forum crawler system determines whether links are informative based on whether they are part of the overall structure of the web site or are used to select sequential information that has been split onto multiple web pages.

摘要： While browsing, a user may interact with a wide variety of images. The user may upload and share images taken with a digital camera and/or search for image using a search engine. Because images are rich in contextual information, it may be advantageous to provide additional information, such as adjacent market advertising based upon matching advertisements with contextual information of the images. Accordingly, a query image may be used to retrieve a video frame set. The video frame set may be expanded with related video frames corresponding to adjacent markets. The expanded video frame set may be grouped into clusters of similar frames. The clusters may be used to rank advertisements based upon how similar the advertisements are to the clusters and/or video frames within the clusters. In this way, one or more ranked advertisements may be presented with the query image.
摘要翻译： 在浏览时，用户可以与各种图像进行交互。 用户可以上传和共享用数码相机拍摄的图像和/或使用搜索引擎来搜索图像。 由于图像丰富的上下文信息，提供附加信息可能是有利的，例如基于匹配广告的相邻市场广告与图像的上下文信息。 因此，可以使用查询图像来检索视频帧集合。 视频帧集可以用对应于相邻市场的相关视频帧进行扩展。 扩展的视频帧集可以被分组成类似帧的簇。 群集可以用于基于广告与群集内的群集和/或视频帧的相似度来对广告进行排名。 以这种方式，可以向查询图像呈现一个或多个排名的广告。
