The optimized image can visually enhance the appearance of the objects that increase the user's comprehension. The optimized image is displayed to the user, via the see-through display device.

Techniques for eliminating one or more portions of a data object from any join step of an operation that joins multiple data objects include determining that an operation joins a first data object and a second data object. The second data object includes multiple portions. Each of multiple data units of the first data object is scanned. Based on data in the data units of the first data object, information is generated. The information indicates a portion of the second data object for exclusion. The indicated portion is excluded from an output of the operation. Only one or more portions of the second data object that are not indicated for exclusion in the information are included in a particular join step involving the second data object. By pruning a large second table, such as a fact table, the computational resources consumed by the joins are substantially reduced.

A distributed content item recommendation system comprises a central recommendation server (101) and a plurality of remote recommendation devices (103) coupled to the central recommendation server (101) via a communication network (105). The central recommendation server (101) stores content item set correlation data for sets of content items. The correlation data is used for item based collaborative filtering in recommendation processors (303) of the recommendation devices (103). A computation task processor (207) maintains a task list of content item correlation computation tasks which can be independently executed to generate content item set correlation data. A task assignment processor (209) can assign the computation tasks to remote recommendation devices (103) which comprise a processing unit (307) that calculates the associated correlation data and returns it to the recommendation server (101). The distributed recommendation system thus uses distributed computation of centrally stored correlation data thereby substantially reducing the cost and complexity of the recommendation server and / or improves the recommendations.

A method of generating a user profile initially comprises receiving (201, 203) characterising data, and optionally user preferences, for content items. The characterising data describes characteristics, such as content or context characteristics, of each content item.

For each content item cluster, cluster characterising data is determined (207) in response to characterising data and possibly user preferences associated with each content item in the content item cluster. First characterising data is then received (209) for a first content item and a first content item cluster is selected (211) in response to a comparison of the first characterising data and the cluster characterising data of each content item cluster. A user profile is then generated (211) for the first content item in response to first cluster characterising data of the first content item cluster.

Accordingly, both the quick transient response and steady state precision positioning can be achieved. The present method can overcome the disadvantages of current controller, which can not reach the desired transient and steady state responses simultaneously.

A website is navigated automatically in a sequential manner, for example by performing a series of specific network requests in a specified order, without necessarily using a browser, and without necessarily rendering each web page in the sequence. Interactions with a website are automatically recorded, stored, and analyzed. Requests and responses can be associated with particular input / output operations. Based on the analysis, the system can determine what data is expected by web servers, so that it can effectively simulate browser operations in connection with those web servers, and extract useful information from the data received in response to those operations. Thus, data extraction and / or other operations can be performed more efficiently and more quickly, while reducing the computing resources needed.

A method and system for reducing the resolution of media data. Input data at a first resolution are received from a source. The input data are compressed. The input data can be downsampled to generate compressed downsampled data at a reduced resolution. The compressed downsampled data can be used to generate a frame at the reduced resolution. When the frame is needed as a reference for another frame, the compressed downsampled data can be decoded to generate decompressed downsampled data at the reduced resolution. Motion compensation is performed on the decompressed downsampled data at the second resolution to generate motion compensated decompressed downsampled data used as a reference for a second frame. Thus, by performing motion compensation on downsampled data directly, data processing operations such as transcoding can be accomplished quickly and effectively while saving computing resources.

A device for segmenting an image comprises a user input (301, 305, 307) for receiving segment indications and boundary indications for the image. Each segment indication identifies a set of pixel regions and a relationship between the set of pixel regions and an associated segment class of a plurality of segment classes. Each boundary indication identifies a boundary between pixels belonging to different segment classes. A segmentation processor (309) then segments the image into the plurality of segment classes in response to both the number of segment indications and the number of boundary indications. Specifically, a propagation of values linking the pixel regions to segment classes are propagated based on the segment indications with the propagation being constrained (e.g. attenuated or blocked) by the boundary indications. The invention may improve or facilitate interactive image segmentation e.g. for frames of a video signal.

A shuffle with proof having a method for proof generating with small computational resources proportionate to the number of input encrypted messages and a corresponding method for verification. Shuffle is represented by a generalized transformation. Combining a proof that the transformation information is retained and a proof of a condition under which the transformation is met constitute the proof for shuffle. The two proofs are short proportional to the number of input encrypted messages. Transformation information retention is proved in such a manner that, since the response is generated from challenge value in dependency upon transformation, the condition under which the transformation is met is reflected in the response-challenge value relation. If the condition under which the transformation corresponding to the shuffle is selected as the condition for proof, the two proofs may constitute the proof for shuffle.

Aggregates are calculated from a data stream in which data is sent in a sequence of tuples, in which each tuple comprises an item identifier and a timestamp indicating when the tuple was transmitted. The tuples may arrive at a data receiver out-of-order, that is, the sequence in which the tuples arrive are not necessarily in the same sequence as their corresponding timestamps. In calculating aggregates, more recent data may be given more weight by a decay function which is a function of the timestamp associated with the tuple and the current time. The statistical characteristics of the tuples are summarized by a set of linear data summaries. The set of linear data summaries are generated such that only a single linear data summary falls between a set of boundaries calculated from the decay function and a set of timestamps. Aggregates are calculated from the set of linear data summaries

Multiple text parts of a body of an incoming e-mail are determined. For each text part, based on natural language processing, a topic category and a feature vector representation (FVR) are determined. For two text parts comprising a common topic category, a similarity value based on their FVR is calculated, and in case the similarity value fulfills a condition, the two text parts are aggregated into one aggregated text part. For each text part: a reference document is selected based on a FVR of the text part; a recipient is obtained based on the corresponding topic category; and an e-mail comprising the text part, and each selected reference document or a pointer thereto, is sent to the obtained recipient. Via aggregation of text parts based on FVR, computational resources for document retrieval based on FVR is reduced, as well as the number of outgoing e-mails.
