Abstract: A method of operating a recommendation system comprises receiving an indication that a first user has knowledge of a first media item, and receiving an indication that a second user has expressed interest in the first media item, wherein the first user and the second user are associated. The first user is prompted to recommend the first media item to the second user, based on the first user's knowledge of the media item and the second user's indication of interest in the media item.

Abstract: A method of generating media pair similarity ratings comprises presenting a user with a first media item, and querying the user regarding additional media items that are most similar to the first media item. Input is received from the user indicating the additional media items that are most similar to the first media item; and a pair similarity rating is set for the first media item and at least one of the additional media items based at least in part on the input indicating the additional media items most similar to the first media item.

Abstract: A method of matching media objects comprises identifying an unknown media item as being the same media item as one of a plurality of known media items by comparing identifying information of the unknown media item with identifying information of one or more known media items. Comparing the identifying information comprises generating a match score for the unknown media item and at least one of the plurality of known media items by comparing the identifying information and determining that the media items match if the match score exceeds a fuzzy match threshold score. If the match score is below the fuzzy match threshold score but above a weak match threshold score, a crowdsource determination of whether the media items match is generated by receiving from two or more users a user determination of whether the media items match.

Abstract: A method of providing multi-person media item recommendations comprises receiving media preference information for a plurality of users, and generating a composite media recommendation score for a plurality of media items for a specified group of at least two of the plurality of users using the media preference information for the two or more users for the plurality of media items. A media recommendation is provided for the specified group of at least two of the plurality of users based on the generated composite media recommendation scores for the plurality of media items for the specified at least two of the plurality of users.

Abstract: Peer-to-peer media item recommendations are provided by presenting a selected list of media items to a first user to consider for recommendation to a friend, receiving an indication from the first user that one or more of the presented media items are to be recommended to the friend, and presenting the one or more indicated media items to the friend. The presented list comprises media items the friend hasn't rated, and is selected using a media recommendation engine.

Abstract: Media is recommended to a user based on domain knowledge and correlation-based recommendation scores. A domain knowledge-based recommendation score is calculated for a user, and a correlation-based recommendation score is calculated for the user. A user recommendation score is calculated for the user regarding a media item, derived from the domain knowledge-based recommendation score and the correlation-based recommendation score. One or more media items are recommended to the user, such as by ordering or selecting media based on their user recommendation scores.

Abstract: Media preference ratings are consolidated by receiving one or more first media item ratings for a user using a first rating system, and receiving one or more second media item ratings for the user from a third party using a second rating system. The one or more second media item ratings from the second rating system are translated into media item ratings in the first rating system, and the one or more media item ratings from the third party translated in the first rating system are combined with the one or more first media item ratings to form a composite media item rating set.

Abstract: Multiple cameras are placed at a site to optimize observability of motion paths or other tasks relating to the site, according to a quality-of-view metric. Constraints such as obstacles may be accommodated. Image sequences from multiple cameras may be combined to produce a virtual sequence taken from a desired location relative to a motion path.

Abstract: The present invention provides a field generating membrane electrode for contact with an electrolyte solution comprising a wetable membrane which is ion permeable under electric field conditions and an electrically conductive material for connection with a source of electrical charges, characterized in that one side of the membrane is in direct contact with the electrolyte solution and the other side of the membrane is in direct contact with the electrically conductive material and a gas receiving volume. The electrode according to the present invention is especially useful for electrokinetic transport, electrokinetic pumping, electrophoretic transport, isotachophoretic transport, separation of ions or electrochemical reaction of ions.

Abstract: A method is provided in which three-dimensional models are created from a number of two-dimensional images, e.g., a video stream of two-dimensional images or still images, using a single camera without prior knowledge of the position or orientation of the camera, its focal length, etc. The method derives a relative value related to the position or orientation of the camera for each two-dimensional image and then, based on the derived position or orientation, uses “ray casting” to develop the three-dimensional model based on intersecting rays through common features of sequential two-dimensional images.

Abstract: A method for creating a three dimensional, textured model of at least one object is provided. The method includes identifying regions of the at least one object in a number of two dimensional images of the at least one object. The method further interrelates the regions identified from the two dimensional images and stores data concerning the region, including its texture, in a data structure that represents the model of the object.
