摘要： A confidentiality preserving system and method for performing a rank-ordered search and retrieval of contents of a data collection. The system includes at least one computer system including a search and retrieval algorithm using term frequency and/or similar features for rank-ordering selective contents of the data collection, and enabling secure retrieval of the selective contents based on the rank-order. The search and retrieval algorithm includes a baseline algorithm, a partially server oriented algorithm, and/or a fully server oriented algorithm. The partially and/or fully server oriented algorithms use homomorphic and/or order preserving encryption for enabling search capability from a user other than an owner of the contents of the data collection. The confidentiality preserving method includes using term frequency for rank-ordering selective contents of the data collection, and retrieving the selective contents based on the rank-order.

摘要： Bit reductions in program instructions are achieved by determining the set of bit patterns in bit locations of the instructions. If only a subset of bit patterns is present in the instructions, they may be represented by an index value having a smaller number of bits. The index value may be substituted into the instruction and later used in decoding by referencing a corresponding bit pattern in a lookup table. The bit-reduction in the instruction makes way for supplemental data bits which may then be embedded.

摘要： Methods and apparatuses are provided for facilitating group access controls in peer-to-peer or other similar overlay networks. A group administrator may create a group in the overlay network and may assign peer-specific certificates to each member of the group for indicating membership in the group. A group member peer node can access data objects in the overlay network using its respective peer-specific certificate to authenticate itself as a group member. The authentication is performed by another peer node in the network. The validating peer node can authenticate that the group member is the rightful possessor of the peer-specific certificate using a public key associated with the peer node to which the peer-specific certificate was issued. The validating peer node can also validate that the peer-specific certificate was properly issued to the group member using a public key of the apparatus that issued the peer-specific certificate.

摘要： A vision based tracking system in a mobile platform tracks objects using groups of detected lines. The tracking system detects lines in a captured image of the object to be tracked. Groups of lines are formed from the detected lines. The groups of lines may be formed by computing intersection points of the detected lines and using intersection points to identified connected lines, where the groups of lines are formed using connected lines. A graph of the detected lines may be constructed and intersection points identified. Interesting subgraphs are generated using the connections and the group of lines is formed with the interesting subgraphs. Once the groups of lines are formed, the groups of lines are used to track the object, e.g., by comparing the groups of lines in a current image of the object to groups of lines in a previous image of the object.

摘要： A three-dimensional pose of the head of a subject is determined based on depth data captured in multiple images. The multiple images of the head are captured, e.g., by an RGBD camera. A rotation matrix and translation vector of the pose of the head relative to a reference pose is determined using the depth data. For example, arbitrary feature points on the head may be extracted in each of the multiple images and provided along with corresponding depth data to an Extended Kalman filter with states including a rotation matrix and a translation vector associated with the reference pose for the head and a current orientation and a current position. The three-dimensional pose of the head with respect to the reference pose is then determined based on the rotation matrix and the translation vector.
