摘要:
The identification of hidden data, such as feature-based control points in an image, from a set of observable data, such as the image, is achieved through a two-stage approach. The first stage involves a learning process, in which a number of sample data sets, e.g. images, are analyzed to identify the correspondence between observable data, such as visual aspects of the image, and the desired hidden data, such as the control points. Two models are created. A feature appearance-only model is created from aligned examples of the feature in the observed data. In addition, each labeled data set is processed to generate a coupled model of the aligned observed data and the associated hidden data. In the image processing embodiment, these two models might be affine manifold models of an object's appearance and of the coupling between that appearance and a set of locations on the object's surface. In the second stage of the process, the modeled feature is located in an unmarked, unaligned data set, using the feature appearance-only model. This location is used as an alignment point and the coupled model is then applied to the aligned data, giving an estimate of the hidden data values for that data set. In the image processing example, the object's appearance model is compared to different image locations. The matching locations are then used as alignment points for estimating the locations on the object's surface from the appearance in that aligned image and form the coupled model.

Methods, system, and apparatus, including computer programs are encoded on a computer storage medium, for providing content based on geographic location data. In one aspect, a method includes receiving a request from a website for a map segment corresponding to a particular location. Keywords are extracted from the website as targeting criteria for the particular location. The targeting criteria is associated with the particular location. A subsequent request for advertising content associated with the particular location is received. One or more advertising content items are selected based on the targeting criteria. The selected advertising content items are provided responsive to the subsequent request.

A combined fingerprint is generated for a video that can match two near-identical videos that differ only in their aspect ratios or formats. A transformation strategy is selected by selecting a first and a second aspect correction method. A first transformed video is generated by applying the first aspect correction method to the video. A second transformed video is generated by applying the second aspect correction method to the video. A first fingerprint is generated using the first transformed video. A second fingerprint is generated using the second transformed video. The combined fingerprint is generated by combining the first half of the first fingerprint with the second half of the second fingerprint.

Methods, systems, and computer program products, including computer programs encoded on a computer readable storage medium, for providing content to a user based on the mode of the user. A method includes: providing a data structure that includes query logs; processing query logs to determine candidate queries that satisfy a criteria, the processing including determining a location of interest, if any, for each query log entry and where the criteria requires an entry to have been submitted from a location that is different from a location of interest associated with the entry; evaluating the candidate queries to determine targeting information for the location of interest; receiving a request for content from a user that is proximate to the location of interest or has expressed an interest in the location of interest; and providing content to the user based at least in part on the targeting information.

A method includes receiving search queries. Images are generated that represent the volume of each search query relative to all search queries over a period of time. The images are processed to generate wavelets for each image. Related queries having similar increases or decreases in volume are identified by comparing at least some of the wavelets corresponding to a first query to wavelets corresponding to other queries.

Videos are received and indexed based on fingerprints generated for the videos, using lookup keys which correspond to sub portions of the reference fingerprints. Specifically, a set of lookup keys is selected such that the number of reference fingerprints such that the clumping associated with the associated each of the lookup keys is minimized. Clumping occurs when a number of reference identifiers associated with a lookup key exceeds a maximum value.

In one embodiment, the present invention recites a coordinating component for creating an enhanced representation of an ongoing event using inputs from a communication session established between a plurality of communication devices. A first input port receives a first input from a first of the plurality of communication devices. A second input port receives a second input from a second of the plurality of communication devices. The first of the plurality of communication devices and the second of the plurality of communication devices do not have a prior association. A generator for selectively combining the first input and the second input creates an enhanced representation of the ongoing event. The enhanced representation is then output from an output port.

Methods and systems thereof for monitoring the performance of a streaming media server are described. A quality-of-service criterion is accessed. A failure to satisfy the quality-of-service criterion during streaming of data from the server to a plurality of clients is identified without assembling the data at the plurality of clients.
