摘要:
Briefly, some embodiments of the invention may provide devices, systems and methods to estimate, detect and handle cross-correlation between co-channel interference and a received signal in a wireless communication network. For example, a method in accordance with an embodiment of the invention may handle a data block of a received signal based on an estimated cross-correlation between co-channel interference and the received signal.

Pose and gesture detection and classification of a human poses and gestures using a discriminative ferns ensemble classifier is provided. Sample image data in one or more channels includes a human image. A processing device operates on the sample image data using the discriminative ferns ensemble classifier. The classifier has set of classification tables and matching bit features (ferns) which are developed using a first set of training data and optimized by a weighting of the tables using an SVM linear classifier configured based on the first or a second set of pose training data. The tables allow computation of a score per pose class for the image in the sample data and the processor outputs a determination of the pose in the sample depth image data. The determination enables the manipulation of a natural user interface.

In one embodiment, the present invention includes a method for training a Support Vector Machine (SVM) on a subset of features (d′) of a feature set having (d) features of a plurality of training instances to obtain a weight per instance, approximating a quality for the d features of the feature set using the weight per instance, ranking the d features of the feature set based on the approximated quality, and selecting a subset (q) of the features of the feature set based on the ranked approximated quality. Other embodiments are described and claimed.

摘要:
A social network application may identify images having common links between a first user's image collection and a second user's image collection. The common links may be identified through metadata or similar portions of the images. Using the first user's image collection, elements of interest may be identified and compared to a second user's image collection to find matches. When matches are found, the results may be selected from groups of results to show a diverse set of matches. The user may be presented with options to select and add matched images to the user's collection, as well as to browse more images that match one or more of the groups.
摘要:
A receiver includes a channel length determination unit to determine a channel length for use by a channel estimator. In at least one embodiment, an iterative process is used to find a channel length (or a combination of channel length and one or more other channel related parameters) that optimizes a channel estimation quality criterion. A time tracking method is also provided that uses an early metric, a center metric, and a late metric to determine an appropriate timing.
