| 20090092300 | System and Method for Lesion Detection Using Locally Adjustable Priors - According to an aspect of the invention, a method for training a classifier for classifying candidate regions in computer aided diagnosis of digital medical images includes providing a training set of annotated images, each image including one or more candidate regions that have been identified as suspicious, deriving a set of descriptive feature vectors, where each candidate region is associated with a feature vector. A subset of the features are conditionally dependent, and the remaining features are conditionally independent. The conditionally independent features are used to train a naïve Bayes classifier that classifies the candidate regions as lesion or non-lesion. A joint probability distribution that models the conditionally dependent features, and a prior-odds probability ratio of a candidate region being associated with a lesion are determined from the training images. A new classifier is formed from the naïve Bayes classifier, the joint probability distribution, and the prior-odds probability ratio. | 04-09-2009 |
| 20100034440 | Anatomical Primitive Detection - A method of detecting an anatomical primitive in an image volume includes detecting a plurality of transformationally invariant points (TIPS) in the volume, aligning the volume using the TIPs, detecting a plurality landmark points in the aligned volume that are indicative of a given anatomical object, and fitting a target geometric primitive as the anatomical primitive based using the detected landmark points. | 02-11-2010 |
| 20100232686 | HIERARCHICAL DEFORMABLE MODEL FOR IMAGE SEGMENTATION - Described herein is a technology for facilitating deformable model-based segmentation of image data. In one implementation, the technology includes receiving training image data ( | 09-16-2010 |
| 20110044534 | HIERARCHICAL CLASSIFIER FOR DATA CLASSIFICATION - Described herein is a framework for constructing a hierarchical classifier for facilitating classification of digitized data. In one implementation, a divergence measure of a node of the hierarchical classifier is determined. Data at the node is divided into at least two child nodes based on a splitting criterion to form at least a portion of the hierarchical classifier. The splitting criterion is selected based on the divergence measure. If the divergence measure is less than a predetermined threshold value, the splitting criterion comprises a divergence-based splitting criterion which maximizes subsequent divergence after a split. Otherwise, the splitting criterion comprises an information-based splitting criterion which seeks to minimize subsequent misclassification error after the split. | 02-24-2011 |

According to one embodiment, a method for handling mobile discount certificates can comprise enrolling a plurality of participants in a mobile discount certificate program. For example, the participants can comprise an issuer of the mobile discount certificates and a customer. A program participant profile can be built for each of the participants. One or more mobile discount certificates can be created based on the program participant profiles and can be communicated to the customer. | 08-28-2008 |
| 20090101720 | MANUFACTURING SYSTEM TO PRODUCE CONTACTLESS DEVICES WITH SWITCHES - A contactless device comprises circuitry storing information, a switch having a first position and a second position, and a fusible link. When the fusible link is intact, wireless reading and writing of the information is enabled regardless of the position of the switch. When the fusible link has been parted, wireless reading of the information is enabled when the switch is in the first position, and wireless reading of the information is disabled when the switch is in the second position. The contactless device may be placed in a non-responsive state, and transformed to a responsive state by parting a second fusible link, or by transmitting an authenticating code to the device. The contactless device may be a card, or some other kind of device. | 04-23-2009 |
| 20090215394 | WIRELESS TRANSLATION DEVICE - A translator for translating wireless communications. The translator includes a first antenna configured to carry signals between the wireless translator and a contactless payment reader, and a second antenna configured to carry signals between the wireless translator and a Bluetooth-enabled device. Circuitry operably coupled to both antennas establishes wireless communication with the contactless payment reader via the first antenna and receives from the contactless payment reader a signal comprising a request for information. The circuitry establishes wireless communication with the Bluetooth-enabled device via the second antenna, and requests the information from the Bluetooth-enabled device. The circuitry receives the information from the Bluetooth-enabled device, and relays the information to the contactless payment reader. | 08-27-2009 |
