Abstract: Aspects of depth map generation and post capture focusing and re-focusing are described. According to one embodiment, a depth map is generated. The depth map may include a mapping among relative depth values in a field of view of an image based on a difference between pixels of a first image and pixels of a second image. An edge map may also be generated by identifying edges in at least one of the first image or the second image. Using the depth map and the edge map, the relative depth values in the depth map may be smoothed using the edge map. In this manner, certain discontinuities in depth values may be smoothed within edge-bounded regions defined by the edge map. The depth map may be used for focusing and re-focusing, for example, or for object extraction, scene understanding, or gesture recognition, among other imaging processes.

Abstract: Aspects of calibration of sensors are described. In one embodiment, a characteristic associated with a first or a second sensor is identified. The characteristic may be identified before or after assembly of a device including the first and second sensors. In turn, an operating characteristic of at least one of the first sensor or the second sensor may be adjusted based on the identified characteristic. Further, a first image may be captured with the first sensor and a second image may be captured with the second sensor. An attribute of the second image, for example, may be adjusted to substantially address any difference between the attribute of the second image and a corresponding attribute of the first image using the characteristic for calibration. The adjustments described herein may assist various processing techniques which operate on pairs of images, for example, particularly when a heterogeneous mix of sensors is used.

Abstract: A computer-implemented bioinformatics program annotates human genetic variants by integrating multiple sources of information. The program rapidly filters variants that are unlikely to play a role in the etiology of particular diseases. This filtering may be performed based on such annotations, on clinical profiles and family histories, and on analyses under various inheritance models, in order to classify human variants and identify mutations influencing patients' diseases.

Abstract: The present invention relates to the field of genetic screening. More specifically, the described embodiments concern methods to screen multiple samples, in a single assay, for the presence or absence of mutations or polymorphisms in a plurality of genes. Approaches to screen for the presence or absence of mutations that are associated with Hereditary Nonpolyposis Colorectal Cancer (HNPCC) and approaches to design primers that generate extension products that facilitate the resolution of multiple extension products in a single lane of a gel or in a single run on a column are also provided.

Abstract: The invention provides a decoder of symbols of received data, the data being encoded according to a convolutional encoding scheme and transmitted through a communications channel. The data is punctuated according to a puncturing matrix, and has a plurality of state values which describe a sequence of state transitions. The decoder has a generation unit that accepts the received data for calculating metrics of the transitions thereof. A selector responsive to the generation unit selects a path of transitions corresponding to the path produced by a transmitter of the data stream. A traceback unit maintains historical information representative of sequential decision operations of the selector. A counter is provided for counting illegal state transitions of the path selected by the selector, and a control unit, responsive to the counter, determines a puncture rate and adjusts a puncture phase of the received data.
