| 20090258660 | LOCATION DETERMINATION USING FORMULA - Among other disclosed subject matter, a method includes obtaining, in a mobile device, power information indicating a detected power of respective signals received from multiple transmitters. The method includes determining a location of the mobile device using a formula that uses: locations of the multiple transmitters, a first function of the power information and a second function of respective locations of the multiple transmitters. The method can include recording the determined location. | 10-15-2009 |
| 20100187311 | BLURRING BASED CONTENT RECOGNIZER - Methods, systems, and apparatus, including computer program products, for identifying regions of interest in an image and identifying a barcode in a degraded image are provided. A region of interest is identified by pre-processing an image, generating a binary image based on a metric calculated on the pre-processed image, and analyzing regions of the image identified using connected components and other analysis. A barcode is identified by searching a population of barcodes, degrading ideal image intensity profiles of candidate barcodes, and comparing the degraded ideal image intensity profiles to an image intensity profile of the degraded image. | 07-29-2010 |

| 20110106418 | ADAPTIVE SENSOR-BASED ACTIVITY CLASSIFICATION - An activity state (e.g., stationary or moving) of an intermittently moving mobile device is classified using sensor measurements provided by one or more on-board sensors. The activity state can be determined by a classifier that exploits the separable log-normal distributions of the short-time variance of sensor measurements. The activity state can provide an external non-correlated indication of movement or stationarity to an on-board navigation engine. The on-board navigation engine can use the activity state to improve tracking performance. | 05-05-2011 |
| 20110292051 | Automatic Avatar Creation - A three-dimensional (“3D”) avatar can be automatically created that resembles the physical appearance of an individual captured in one or more input images or video frames. The avatar can be further customized by the individual in an editing environment and used in various applications, including but not limited to gaming, social networking and video conferencing. | 12-01-2011 |
| 20120080515 | Barcode Recognition Using Data-Driven Classifier - A barcode decoding system and method are disclosed that use a data-driven classifier for transforming a potentially degraded barcode signal into a digit sequence. The disclosed implementations are robust to signal degradation through incorporation of a noise model into the classifier construction phase. The run-time computational cost is low, allowing for efficient implementations on portable devices. | 04-05-2012 |
| 20120082396 | Digital Image Resampling - Systems, methods and computer program products are disclosed for resampling a digital image. According to an implementation, a source image can be presharpened and upsampled to a first upsampled image having a specified image size and a first level of presharpening. The source image is also presharpened and upsampled to a second upsampled image having the specified image size and second level of presharpening that is less than the first level of presharpening. The first and second upsampled images are deblurred. A binary edge mask image is generated from the deblurred, upsampled images. The binary edge mask image is dilated and blurred to generate a deep mask image. The first and second, deblurred upsampled images are blended together using the deep mask image. | 04-05-2012 |
