摘要： In customizing a user profile employed by a recommendation system, users are prompted for feedback regarding content that is the subject of the recommendation system. Only feedback that does not degrade performance of the recommendation system, as measured by the error rate, is accepted and utilized to modify the user profile. Feedback that would degrade performance is discarded without being employed to alter the user profile. In this manner, error is continually driven toward a minimum by system changes based on feedback.

摘要： Extracting and processing video content encoded in a rendered color space to be emulated by an ambient light source, comprising extracting color information from a video signal and transforming the color information through unrendered color space using tristprimary matrices to form a second rendered color space to drive the ambient light source. Video signal decoding into frames can allow extracting average or other color information from an selected screen regions to reduce bitstream load, and negative gamma correction helps prevent garish or inappropriate chromaticities and luminance.

摘要： A program recommender (300) that receives one or more starring actor data fields for a program. The recommender adjusts one or more of the received starring actor data fields (600) by utilizing a source separate from the received starring actor data fields to identify one or more starring actors in the program. The adjusted data fields may be made available for use in creating a viewer profile (400), or alternatively may be made available for determining a recommendation (330) for the program.

摘要： Artificial intelligence applications require use of training sets containing positive and negative examples. Negative examples are chosen using distributions of positive examples with respect to a dominant feature in feature space. Negative examples should share or approximately share, with the positive examples, values of a dominant feature in feature space. This type of training set is illustrated with respect to content recommenders, especially recommenders for television shows.

摘要： Methods and apparatus are disclosed to various embodiments for recommending items (150) to an advisee such as television program recommendations, based on other user's viewing preferences (140) or profiles (160). In contrast to the state of the art, the other user's have at least one demographic in common with the advise, such as age, income or gender for example or combinations thereof. According to one aspect of the invention, recommendations may be generated before a viewing or purchase history of the advisee is available. According to one embodiment, a method for recommending items includes the acts of receiving a recommendation request from an advisee for a recommendation of said items; filtering a general population of users to identify a sub-population of users who share at least one demographic in common with said advisee; computing a degree of closeness measure between preference data associated with each user in the sub-population and one of preference (140) and profile (160) data associated with said advisee; selecting the preference data associating with N users from said sub-population having the lowest computed degree of closeness measure with the advisee, where N is a positive integer value, equal to or greater than 1; using the selected preference data to recommend said items to the advisee.

摘要： A method and apparatus are disclosed for generating and maintaining enhanced background models for use in background-foreground segmentation. Background models are modified to contain an indication of objects that are typically stationary. Thereafter, if an object moves and has been previously identified as an object that is typically stationary, the object will not unnecessarily be identified as part of the foreground during background-foreground segmentation. In an exemplary implementation, moving objects are classified into two sets. A first set includes objects that typically move independently and a second set includes objects that are typically stationary. Generally, once an object is assigned to the second (stationary object) set, the object will remain in the background, even if the object is moved (normally, movement of the object would cause the object to become part of the foreground).

摘要： A method and apparatus are disclosed for automatically learning and identifying events in image data using hierarchical HMMs to define and detect one or more events. The hierarchical HMMs include multiple paths that encompass variations of the same event. Hierarchical HMMs provide a framework for defining events that may be exhibited in various ways. Each event is modeled in the hierarchical HMM with a set of sequential states that describe the paths in a high-dimensional feature space. These models can then be used to analyze video sequences to segment and recognize each individual event to be recognized. The hierarchical HMM is generated during a training phase, by processing a number of images of the event of interest in various ways, typically observed from multiple viewpoints.

摘要： Aspects of the present invention can be configured to demultiplex an asynchronously multiplexed video signal, which comprises images from a number of different cameras. Image matching techniques are used to assign input images with states. After a period, the number of states will generally equal the number of input cameras. The states may be modeled through any number of techniques, such as histogram analysis, clustering, and hidden Markov model analysis. Input images are assigned to states, and the input images are output as being associated with the states. Zone surveillance may be performed on a series of images from one or more of the states. Any events that occur can be distinguished and reported.
