Abstract: Disclosed is a method and apparatus for biometric based media data sharing. The method may include initiating, in a first device, biometric data capture of a user based, at least in part, on playback of media data by the first device. The method may also include determining that captured biometric data of the user does not correspond with biometric data associated with an authorized user of the first device. Furthermore, the method may also include in response to a failure to match the captured biometric data by the first device, establishing that the user is an authorized user of a second device based, at least in part, on the captured biometric data. The method may also include sharing the media data with the second device.

Abstract: A method for obtaining structural information from a digital image by an electronic device is described. The method includes determining an iris position in a region of interest based on a gradient direction transform. Determining the iris position may include determining a first dimension position and a second dimension position corresponding to a maximum value in the transform space.

Abstract: A method includes receiving first data defining a first bounding box for a first image of a sequence of images. The first bounding box corresponds to a region of interest including a tracked object. The method also includes receiving object tracking data for a second image of the sequence of images, the object tracking data defining a second bounding box. The second bounding box corresponds to the region of interest including the tracked object in the second image. The method further includes determining a similarity metric for first pixels within the first bounding box and search pixels within each of multiple search bounding boxes. Search coordinates of each of the search bounding boxes correspond to second coordinates of the second bounding box shifted in one or more directions. The method also includes determining a modified second bounding box based on the similarity metric.

Abstract: A method for detecting and tracking a target object is described. The method includes performing motion-based tracking for a current video frame by comparing a previous video frame and the current video frame. The method also includes selectively performing object detection in the current video frame based on a tracked parameter.
