  • Publication number: 20140324888
    Abstract: A method, apparatus and computer program product are provided to permit improve gesture recognition based on fusion of different types of sensor signals. In the context of a method, a series of image frames and a sequence of radar signals are received. The method determines an evaluation score for the series of image frames that is indicative of a gesture. This determination of the evaluation score may be based on the motion blocks in an image area and the shift of the motion blocks between image frames. The method also determines an evaluation score for the sequence of radar signals that is indicative of the gesture. This determination of the evaluation score may be based upon the sign distribution in the sequence and the intensity distribution in the sequence. The method weighs each of the evaluation scores and fuses the evaluation scores, following the weighting, to identify the gesture.

  • Publication number: 20130271370
    Abstract: A free hand gesture control user interface is described. Components of the interface system may include a stereo vision camera, or multiple cameras, a control unit, a projector and a projecting surface. In an automotive application, the projecting surface may be the windscreen in the vehicle or a mounted screen. The camera together with software modules in the control unit define a gesture acceptance border and a gesture acceptance space within which hand gestures may be imaged, defined for various control actions, and executed. The hand images are analyzed in slices of the gesture acceptance space to determine hand orientation (open or closed) and/or motion.

  • Publication number: 20130251274
    Abstract: An example apparatus is caused to receive a video sequence of a plurality of frames, and perform a number of operations as each of at least some of the frames is received but before all of the frames are received. The apparatus is caused to calculate a score for the frame, and compare the score for the frame to a predefined threshold. The apparatus is caused to cause output of the frame as a key frame in an instance in which the frame is received within a specified period of time and the score for the frame is above the predefined threshold. Otherwise, in an instance in which none of the scores for frames received within the specified period of time is above the predefined threshold, the apparatus is caused to cause output of one of the frames received within the specified period of time as a key frame.

    Abstract: An approach is provided for providing collaborative recognition using media segments. The recognition platform causes, at least in part, a generation of a request to determine recognition information for one or more media items associated with a device, one or more segments of the one or more media items, or a combination thereof. Next, the recognition platform determines to transmit the request to one or more other devices based, at least in part, on one or more device selection criteria. Then, the recognition platform receives the recognition information in response to the request. Further, the recognition platform processes and/or facilitates a processing of the recognition information to determine one or more identities of one or more users, one or more objects, or a combination thereof represented in the one or more media items.
