    摘要： A method for rendering a deformable object. The method includes: obtaining a 3D volumetric voxel dataset of a region, such region having therein an object to be rendered; building a tree hierarchical structure for the obtained volumetric dataset, such tree structure blocks as the nodes of a primary tree hierarchy and bricks being those blocks stored as textures in a video memory; augmenting the primary tree hierarchical structure with maximum and minimum values of the data contained within a block; creating a neighborhood tree hierarchy having for each leaf block of the neighborhood tree hierarchy a reference to the neighboring leaf blocks in the neighborhood tree hierarchy as well as references to neighboring bricks in the neighborhood tree hierarchy; updating the information about minimum and maximum in the primary tree hierarchy by saving for each block the minimum and maximum of the neighboring blocks; and rendering the leaf blocks in visibility order.

    摘要： A method, system, and computer program product for counting predictor-target pairs for a decision tree model provides the capability to generate count tables that is quicker and more efficient than previous techniques. A method of counting predictor-target pairs for a decision tree model, the decision tree model based on data stored in a database, the data comprising a plurality of rows of data, at least one predictor and at least one target, comprises generating a bitmap for each split node of data stored in a database system by intersecting a parent node bitmap and a bitmap of a predictor that satisfies a condition of the node, intersecting each split node bitmap with each predictor bitmap and with each target bitmap to form intersected bitmaps, and counting bits of each intersected bitmap to generate a count of predictor-target pairs.

    摘要： A method for implementing messaging services includes receiving a message body sent by a calling user, determining whether the calling user and a called user are in the same IP Multimedia Subsystem (IMS) domain according to user registration information, and sending the message body to the called user if the calling user and the called user are in the same IMS domain. An IMS messaging service system includes a Message Application Server (MAS), a Call Session Control Function (CSCF) entity, a calling User Equipment (UE) and a called UE. A MAS includes a user registration information storing unit, a receiving unit, and a determining unit adapted to determine whether the calling user and the called user are in the same IMS domain according to the user registration information stored in the user registration information storing unit when the receiving unit receives the message body from the calling user, and a sending unit. According to embodiments of the present disclosure, when the calling user and the called user are in the same IMS domain, the information interaction process and the message body transmission time may be shortened.

    摘要： A method for enhancing video or other multimedia in order to achieve a closer-to-movie theater viewing experience. The enhancement method can be applied to YUV or other video formats which are used for TV or digital media. The method provides a curve with at least one inflection point such that at least one region has a concave upward arc and another region has a concave downward arc. The improved curve provides relatively less contrast in relatively dark regions and relatively more contrast in relatively bright regions. By taking into account the visual sensitivity to various luminance levels, a neutral point is selected to be located at a relatively dark point. To the darker side of the neutral point, luminance is suppressed. To the brighter side of the neutral point, luminance is enhanced. This luminance-mapping curve is applied to the luminance (Y) signal so as to enhance both brightness and contrast.

    摘要： A method encrypting data including selecting a pair of sequences based on a seed, performing a transposition of the data utilizing elements of a first one of the pair of sequences to produce a first transposition result, and performing a transposition of the first transposition result utilizing elements of a second one of the pair of sequences to produce the encrypted data. The pair of sequences may be selected from a pool of constrained sequences. The pool of constrained sequences may be generated utilizing a Knights Tour sequence generating system. The pool of constrained sequences may be transferred to a decrypting device for decryption of the encrypted data. The pair of sequences may be randomly generated utilizing a random integer sequence generator and the seed. The constrained indication may be constrained to a number of sequences present in the pool of sequences.
