摘要： A sequence of images depicts a foreground object in motion. A base image is selected, and the other images in the sequence are co-registered with the base image in order to align the images to a common coordinate system. A background image and a binary foreground mask are generated from the sequence of aligned images. By applying the foreground mask to a chosen one of the aligned images, a representation of the moving object is extracted. After blurring the background image, the extracted representation may be superimposed onto the blurred background image to produce a new image.

摘要： The subject disclosure is directed towards using a satisfaction model's prediction as to whether a user was satisfied or dissatisfied in satisfying a search goal to help estimate the relevance of a URL/document that was returned and clicked by the user. The clickthrough data for a search goal session is processed by either a utility model or a despair model based on whether the satisfaction model indicated that the search goal session ended with the user satisfied or dissatisfied, respectively. The utility model distributes a utility value to each clicked URL, while the despair model distributes a despair value to each clicked URL. The utility value and despair value of each query-URL pair may be used as corresponding feature data for learning a search ranker.

摘要： A classifier training system trains unified classifiers for categorizing videos representing different categories of a category graph. The unified classifiers unify the outputs of a number of separate initial classifiers trained from disparate subsets of a training set of media items. The training process takes into account the relationships that exist between the various categories of the category graph by relating scores associated with related categories, thus enhancing the accuracy of the unified classifiers.

摘要： In a wireless network there is a scheduling method in which a base station (BS) acquires information relevant to signal quality between the BS and each mobile terminal and reports to a scheduling apparatus. The scheduling apparatus selects a service BS for each terminal and determines a specific BS to compensate for interference; and may provide further controls to correspondingly transmit service data of the terminal to the service BS. The BS determines the serviced terminal and the terminal of which the interference is eliminated. When servicing the terminal on a time-frequency resource and eliminating the interference from other BS, the BS may only acquire channel state information of the terminal associated with the BS to the BS on the corresponding time-frequency resource and calculate a pre-coded matrix, so as to pre-code terminal service data from the service BS and generate downlink signals to be transmitted.
