Abstract: An electronic device for gesture recognition on resource-constrained devices is provided. The electronic device controls storage of a plurality of first consecutive image frames in a first buffer of a first length. The plurality of first consecutive image frames corresponds to the first length. The electronic device recognizes a first hand sign of a plurality of hand signs in a first subset of image frames of the plurality of first consecutive image frames. The electronic device controls storage of the recognized first hand sign in a second buffer of a second length based on the determination that a ratio of a number of the first subset of image frames and the first length is one of equal to or greater than the threshold. The electronic device determines a gesture corresponding to one or more hand signs of the plurality of hand signs stored in the second buffer.

Abstract: In one embodiment, a processing device receives a first digital fingerprint of a media item along with a first content management rule. The processing device separately receives a second digital fingerprint of the media item along with a second content management rule. The processing device determines that the received digital fingerprints are for the same media item based upon a match between the first digital fingerprint and the second digital fingerprint. The processing device determines that all rights to the media item have been accounted for, and then determines a set of actions to be performed for hosted media items comprising the media item based at least in part upon the first content management rule and the second content management rule. Processing logic may also perform a conflict resolution process for conflicting rights claims to the media item.

Abstract: A system collects first data associated with user. The first data includes historical health data and set of sensor data corresponding to a set of health-monitoring parameters. The system applies first Artificial Intelligence (AI) model on the first data to compute indicators which reflect a deviation in a health condition of the user with respect to reference values. Based on the indicators, the system generates first inference data comprising labels or tags associated with a cause of the deviation. Based on the first inference data, the system determines a first requirement for which the user is required to visit a first healthcare center. The system further determines a first set of user-related data associated with the first requirement, based on the first data and the first inference data. Thereafter, the system transfers the first set of user-related data to an electronic healthcare system associated with the first healthcare center.

Abstract: A cluster-based approach and template-based approach are combined to segment brain matter from a three-dimensional MRI image of voxels. The morphological information captured by the template-based approach may be used to refine the segmentation produced by the cluster-based approach. Conversely, the “similarity” information captured by the cluster-based approach may be used to refine the segmentation produced by the template-based approach.

Abstract: In one aspect, a computer-implemented method corrects a multi-sphere head model used in dipole localization for a set of magnetic field sensors (MEG sensors) by replacing ghost spheres with replacement spheres that are not ghost spheres. One type of ghost sphere completely encloses the brain volume but is so large that a center of the sphere is outside the brain volume. Another type of ghost sphere lies entirely outside the brain volume. Various approaches for correcting ghost spheres are disclosed.

Abstract: In one embodiment, a processing device receives a request to claim ownership of a first hosted media item on a first media sharing platform, wherein the request is received from a rights holder that holds one or more rights to a claimed media item that is incorporated into the first hosted media item. The processing device adds an indicator of the ownership of the rights holder to a first entry for the first hosted media item in a data store. The processing device determines that a second hosted media item having a threshold similarity to the first hosted media item is hosted by a second media sharing platform. The processing device automatically adds an indicator of the ownership of the rights holder to a second entry for the second hosted media item without receiving a separate request to claim ownership of the second hosted media item.

Abstract: In one aspect, multiscale filtering is used to normalize the intensities of voxels in an MRI image. A multiscale filter is applied to the raw MRI image. This image is compared to the original image. Luma aberrations (i.e., intensity variations) are corrected based on this comparison. In one approach, the intensity of the image is increased for voxels that are dimmer than in the multiscale filtered version, and decreased for voxels that are brighter than the multiscale filtered version. In another aspect, additional features are created based on multiscale gradients. These may be used in combination with other approaches to segment the MRI image. Voxels with positive gradients may represent brain gray matter bordered by brain white matter. Voxels with negative gradients may represent brain white matter bordered by brain grain matter.

Abstract: A system assists users in time and frequency analysis of magnetoencephalography (MEG) signals. In one aspect, a system includes an analysis module, a configuration module and a user interface. The analysis module performs a time and frequency analysis of the MEG signal, for example a short time Fourier transform (STFT) or a continuous wavelet transform (CWT) analysis. The analysis is parameterized by a parameter set that affects the time and frequency resolution of the analysis, for example window size and overlap size for STFT or center frequency and decay parameter for CWT. The configuration module automatically determines or assists the user to determine correct values for the parameter set.

Abstract: A surface model is generated from a three-dimensional volume model of a person's head. The person's head is modelled as a three-dimensional volume model of loss values (i.e., absorption values). Wave vectors are launched towards the volume model. Each wave vector is characterized by a wavelength and a capture direction (direction of propagation). The launched wave vectors are absorbed by the volume and the point at which they are absorbed (referred to as the intersection point) is determined. The surface model of the person's head is generated from the intersection points of the wave vectors.
