20150081469 | ASSISTING BUYING DECISIONS USING CUSTOMER BEHAVIOR ANALYSIS - A method, system, and computer program product for assisting buying decisions using customer behavior analysis are provided in the illustrative embodiments. Product information comprising a set of product attributes is received about a grouping of products. Customer behavior information about a behavior of a customer is received from which a set of customer buying behavior factors is extracted. A customer buying behavior factor comprises an inferred preference of the customer for buying a product from the grouping of products. A weight is assigned to a customer buying behavior factor. A set of weighted customer buying behavior factors is mapped to a subset of the product attributes. At least one product is selected from the grouping of products such that the at least one product includes a subset of product attributes, and an overall weighted score of the at least one product exceeds a threshold. | 03-19-2015 |
20150088598 | CROSS-RETAIL MARKETING BASED ON ANALYTICS OF MULTICHANNEL CLICKSTREAM DATA - A method and associated system of cross-retail marketing based on analysis of multichannel clickstream data that comprises a client application capturing, aggregating, and analyzing multiple clickstreams of a user. These clickstreams may be captured from multiple unrelated or competing sales or distribution channels and from multiple electronic platforms. The analysis may use methods of artificial intelligence, text analytics, semantic analytics, or other analytical methods to infer characteristics of the user, of the user's online commercial behavior and other commercial activities, and of products or services that the user may be interested in purchasing. The output of this analysis is forwarded to other channels or platforms visited by the user in order to allow those other channels or platforms to perform targeted commercial marketing functions related to the user's prior activities. In preferred embodiments, this method may be require an active consent or other authorization from the user. | 03-26-2015 |

20080209285 | Method and Circuit for Measuring Operating and Leakage Current of Individual Blocks Within an Array of Test Circuit Blocks - A method and circuits for measuring operating and leakage current of individual blocks within an array of test circuit blocks provides measurement free of error due to leakage currents through non-selected circuit blocks, without requiring an independent test facility for each circuit block. The circuit includes a pair of power supply grids and selection circuits at each test circuit block to select between a test power grid and a “rest” power grid used to supply current to the non-selected circuits. The leakage currents through the non-selected circuits are thus sourced from the rest grid and error that would otherwise be introduced in the test grid current measurement is avoided. The test circuit blocks may be ring oscillators, and the measured current may be the operating and/or leakage current of the ring oscillator. The circuit blocks may also include individual devices for IV (current-voltage) characterization using an additional gate input grid. | 08-28-2008 |
20090138227 | Characterizing Across-Die Process Variation - Measurement of individual quiescent supply currents from multiple power supply pads located across a semiconductor die provides a means of characterizing across-die variation. A ratio is created by combining the individual pad supply current with the sum of all pad supply currents for a given die. An n-tuple is formed from the set of ratios for all pad supply currents to provide a unique signature for different across-die variation profiles. | 05-28-2009 |

20080298666 | Identifying blood vessels in lung x-ray radiographs - A method of detecting blood vessel shadows in an anterior posterior x-ray radiograph comprising the steps of: generating candidate sub areas of the radiograph showing changes in contrast above a threshold level; supressing rib shadow edges; eliminating lung tissue shadow edges, and categorizing and eliminating nodule shadows. | 12-04-2008 |
20080317322 | Identifying Ribs in Lung X-Rays - A method of detecting lung nodules in an anterior posterior x-ray radiograph comprising the steps of: generating candidate regions in image showing changes in contrast above a threshold level, and eliminating false positives by eliminating edges assignable to organs by: identifying edges; categorizing and eliminating rib edges; categorizing and eliminating lung tissue edges, and categorizing and eliminating blood vessels. | 12-25-2008 |
20090052763 | Characterization of lung nodules - A method of identifying nodules in radiological images, said method comprising: (a) obtaining a radiological image; (b) selecting a sub-image centered around a candidate location; (c) dividing the sub-image into a rectangular array of cells; (d) calculating absolute values of Intensity Differences id | 02-26-2009 |
20100040269 | METHOD AND SYSTEM FOR VERIFYING DETECTION OF A LUNG NODULE - Detected lung nodules are presented in a chest radiographic sub-image. A curve is matched to pixels in the sub-image and confidence values for individual pixels is determined. A confidence image is generated consisting of the confidence values at the position of the respective pixel. Separated regions of pixels within the confidence image are identified which have a confidence value greater than a threshold confidence value. A filtered confidence image is generated consisting of the separated regions of the confidence image which are larger than a threshold area. A histogram of values characteristic for the matching of the curve is determined, wherein the filtered confidence image is used as a mask, such that only values are considered for the histogram which correspond to the separated regions of the filtered confidence image. A statistical measure of the histogram is determined and the lung nodules are verified based on the statistical measure. | 02-18-2010 |
20100303358 | METHOD FOR THE AUTOMATIC ANALYSIS OF IMAGE DATA OF A STRUCTURE - A method is described for the automatic analysis of image data of a structure. in at least one embodiment, the method includes: providing image data in the form of a three-dimensional voxel array, performing segmentation of the voxel array in order to determine a voxel subset, performing feature extraction at least for particular voxels of the voxel subset in order to generate a feature map, generating a scalar difference map on the basis of the feature map, performing classification with the aid of the difference map and identifying a structural anomaly in the image data on the basis of a classification result. A method for driving an image display device, an image processing system and an imaging system are furthermore described. | 12-02-2010 |
