20130006947 | CONFLICT RESOLUTION VIA METADATA EXAMINATION - A provided computing device detects a synchronization conflict between two versions of a file and may examine corresponding metadata fields. The computing device may characterize a nature of a difference between metadata fields as immutable, mergeable, or subsumable. Core metadata fields may be defined such that a nature of a difference, or conflict, is categorized as immutable. Non-core metadata fields may be defined such that a nature of a difference, or conflict, is characterized as either mergeable or subsumable. A conflict between corresponding mergeable non-core metadata fields may be resolved by merging values of the corresponding non-core metadata fields. A conflict between corresponding subsumable non-core metadata fields may be resolved by replacing a value of a non-core metadata field of an older of the two versions of the file with a value of a corresponding non-core metadata field of a younger of the two versions of the file. | 01-03-2013 |

20100082692 | METHOD AND APPARATUS FOR CLASSIFICATION OF CORONARY ARTERY IMAGE DATA - A polyline tree representation of a coronary artery tree imaged in a volume data set is obtained, and its topology is extracted to give a topological representation indicating the relative positions of vessels in the tree. The topological representation is compared with a set of topological rules to find possible anatomical classifications for each vessel, and a set of candidate labeled polyline trees is generated by labeling the polyline tree with labels showing each combination of possible anatomical classifications. Each candidate labeled tree is filtered according to a set of geometric rules pertaining to spatial characteristics of vessels in arterial trees, and any labeled tree not satisfying the geometric rules is rejected A figure of merit is calculated for each remaining candidate by comparing features of the vessels measured from the polyline tree and from the volume data set with features of correctly classified vessels in other data sets to determine the probable correctness of the labeling of each candidate, and the candidate with the best figure of merit is selected as showing the proper classification of the vessels. | 04-01-2010 |
20120027272 | IMAGE SEGMENTATION - According to one embodiment there is provided a method of selecting a plurality of M atlases from among a larger group of N candidate atlases to form a multi-atlas data set to be used for computer automated segmentation of novel image data sets to mark objects of interest therein. A set of candidate atlases is used containing a reference image data set and segmentation data. Each of the candidate atlases is segmented against the others in a leave-one-out strategy, in which the candidate atlases are used as training data for each other. For each candidate atlas in turn, the following is carried out: registering; segmenting; computing an overlap; computing a value of the similarity measure for each of the registrations; and obtaining a set of regression parameters by performing a regression with the similarity measure being the independent variable and the overlap being the dependent variable. The M atlases are then selected from among all the N candidate atlases to form the multi-atlas data set, the M atlases being those atlases determined to collectively provide the highest aggregate overlap over all the training data image sets. | 02-02-2012 |

20110144801 | Vending Machine - In an exemplary embodiment of this invention, a vending machine may include sensors for capturing audio and visual data. A processing unit in the vending machine may analyze this data to calculate an attention score that is indicative of whether attention is being paid to the vending machine. Alternatively, or in addition, the processing unit may analyze this data to calculate the gender or emotional state of a person. Based on these calculations, a vending machine may alter its behavior, such as by changing its audiovisual output. | 06-16-2011 |
