    摘要: Technologies are generally described for providing a robust object recognition scheme based on dynamic modeling. Correlations in fine scale temporal structure of cellular regions may be employed to group the regions together into higher-order entities. The entities represent a rich structure and may be used to code high level objects. Object recognition may be formatted as elastic graph matching.

    摘要: Technologies are generally described for tracking an object. In some examples, a system may comprise a mobile phone and an augmented reality device. The mobile phone may be effective to receive a transmitted wave and to receive a reflected wave reflected off of an object. The mobile phone may be configured to determine a difference between the transmitted and the reflected wave, and generate first tracking data based on the determined difference. The augmented reality device may be adapted to receive the first tracking data and determine second tracking data regarding the location of the object based on the first tracking data. An image may be generated on a display based on the determined first and second tracking data.

An example system may comprise a processor, a memory arranged in communication with the processor, and a display arranged in communication with the processor. An example system may further comprise a sensor arranged in communication with the processor. The sensor may be effective to detect measurement data regarding a constrained object. The sensor may be configured to send the measurement data to the processor. The processor may be effective to receive the measurement data, determine a model for the object, and process the measurement data to produce weighted measurement data. The processor may also be effective to apply a filter to the model and to the weighted measurement data to produce position information regarding the object, which may be utilized to generate an image based on the position information.

    摘要: The present invention provides systems and methods for reducing the ‘cold start’ TTFF of navigation receivers. The systems and methods receive geographical information from a user, such as the nearest city, state or country, and use this geographical information to approximate the position of the receiver. The systems and methods then make use of the approximate position to reduce the ‘cold start’ TTFF. In an embodiment, the approximate position of the receiver is determined from a co-ordinate database in the receiver based on the geographical information provided by the user. In another embodiment, a user provides geographical information to the receiver through a displayed map with several stages of zooming capability.

    摘要: Technologies described herein generally provide for an improved augmented reality system for providing augmented reality images comprising a pre-operative image superimposed on a patient image. The accuracy of registering the pre-operative image on the patient image, and hence the quality of the augmented reality image, may be impacted by the periodic movement of an organ. Registration of the pre-operative image on the patient image can be improved by accounting for motion of the organ. That is, the organ motion, which can be described by a dynamical model, can be used to correct registration errors that do not match the dynamical model. The technologies may generate a sequence of 3-D patient images in real-time for guided surgery.

    摘要: Technologies are described herein for generating a diagnostic three dimensional image for a patient. Some example technologies may obtain a sequence of multiple images of the patient using an imaging modality device. The technologies may estimate a registration vector for each image based on a motion function and an image transformation function. Each image may be defined by a measurement noise added to the image transformation function operating on the registration vector with respect to a reference image. The registration vector may be a function of a breathing motion of a prior registration vector added to a transition noise value. The technologies may estimate motion parameters based on the registration vector. The technologies may iteratively refine the registration vector and the motion parameters. The technologies may generate the diagnostic three dimensional image of the patient using the registration vector for each image and the motion parameters.

    摘要: Technologies are generally described for aligning objects in augmented reality. In some examples, a processor may be adapted to receive detected image data and virtual object data. In some examples, the processor may further be adapted to generate and apply weights to log-likelihood functions at intensity and feature levels based on the virtual object data and detected image data. In some examples, the processor may further be adapted to add the weighted log-likelihood function at intensity level to the weighted log-likelihood function at feature level to produce a cost function. In some examples, the processor may further be adapted to determine transformation parameters based on the cost function that may be used to align the detected image data with virtual object data.

    摘要: A method and apparatus are provided for separating signals from a received combined signal in a wireless communication system. Combined signals are received by one or more antennas, demodulated and filtered. The combined signals are mixed with known scrambling codes of a target sector and possibly interfering sectors prior to signal separation, by which a separation matrix is created. The separation matrix is used to provide separate desired and interferer signals, such that the desired signals may be despread with known spreading codes for further decoder processing. In an alternate embodiment, the separation matrix is split according to scrambling and spreading code processing to decrease processing complexity. Feedback adjustment control may be used to adjust separation parameters based on generated separation matrices and separated signals.
